An ellipse tube is more stretched and pointed at the ends than an oval, so an oval plug never quite fits. This one matches that geometry exactly, its flexible PE walls gripping the curved interior with no glue or tools. For hollow ellipse furniture legs. Black and white.
We make this size in production runs, so there is none on the shelf today. Tell us how many you would want and you go on the list for it. When enough people ask for a size, we run it, and the people who asked hear about it first.
We stock a limited range of tube sizes and wall thicknesses. Tell us the size you need and we will confirm availability and pricing by email.

Oval and ellipse look similar at first glance. Both have two different axes and continuous curves. The difference is at the ends: oval tubes have rounded, blunt ends. Ellipse tubes have pointed, tapered ends that taper to a narrower profile. No oval plug fits an ellipse tube correctly because the curves diverge at exactly those pointed ends. Ellipse tube plugs are molded to match the elongated, tapered geometry of true ellipse tubing. The plug body press-fits inside the tube with flexible internal walls that follow the ellipse curve at every point, including the tapered ends where oval plugs fail.
PE (polyethylene) construction. Press-fit installation with no adhesive, no screws, and no tools beyond an optional rubber mallet. Ellipse tube plugs come in : 15 × 30 mm and 20 × 40 mm. Black and white. Ellipse tube plugs for furniture with ellipse tubing on chairs, bar stools, display fixtures, and any application where the tube profile is a true ellipse. Ellipse tube end plugs that seal, protect, and finish every open ellipse tube end.
Three measurements: short axis (width), long axis (length), and wall thickness. ellipse tubing has two different outside dimensions, and both must match the plug specification. Both available sizes share a 2:1 aspect ratio (the long axis is exactly twice the short axis).
Use calipers across the narrowest point of the ellipse opening, outside edge to outside edge. This is the first number in the size designation (15 or 20 mm for ellipse tube plugs).
Use calipers across the widest point of the ellipse, outside edge to outside edge. This is the second number (30 or 40 mm). The long axis is always perpendicular to the short axis and runs through the pointed ends.
Use calipers at the tube end. The 15 × 30 requires 1.5 to 2 mm wall. The 20 × 40 requires 1 to 2 mm wall. Check at both the narrow center and the pointed ends, as wall thickness can vary along the ellipse curve.
Same press-fit concept as all our tube plugs. Ellipse tube plugs must enter the tube with the short axis aligned to the short axis and the long axis aligned to the long axis. The plug will not fit if rotated 90° because the two axes are different lengths. The tapered ends provide a natural alignment guide: the plug’s pointed ends slide toward the tube’s pointed ends.
The same four problems as every other tube plug, applied to a cross-section that only ellipse-specific plugs can handle. The National Wood Flooring Association (NWFA) recommends protective measures on all furniture legs, and ellipse tube plugs provide that protection on hollow ellipse metal profiles.
An open ellipse tube end puts a sharp metal edge on the floor that follows a continuously changing curve, tightest at the pointed ends and gentlest at the wide center. This geometry concentrates floor contact at the pointed ends, which dig into finished surfaces. Ellipse tube plugs cover the entire ellipse opening with a smooth PE head. Unlike leaving metal edges unprotected, the plug distributes weight evenly across the full ellipse area.
An open ellipse tube collects moisture, debris, and insects. On steel tubing, trapped moisture causes internal corrosion that weakens the frame. Ellipse tube plugs seal the entire ellipse opening. The flexible walls conform to the full curve, including the tight radii at the pointed ends where sealing is most challenging. No gaps at any point along the perimeter. Plugs for ellipse furniture legs that seal the full cross-section.
Hollow ellipse tubes resonate and amplify contact noise. The varying curve produces a complex metallic ring when the tube contacts smooth, hard floors. The pointed ends act as natural stress concentrators that amplify vibration. Ellipse tube plugs fill the opening with PE, absorbing the vibration across the full ellipse interior. In restaurants, offices, and schools where ellipse-legged chairs move constantly, sealed ends reduce noise.
ellipse tubing is chosen for its distinctive visual profile: sleeker and more dynamic than standard oval or round. An open tube end undermines that design by exposing the hollow interior. Ellipse tube plugs cover the opening with a clean PE head that follows the ellipse contour exactly, including the tapered endpoints. The finished end reads as intentional, maintaining the tube’s design-forward aesthetic. ellipse tubing plugs PE that complete the design.
If your furniture has ellipse tubing, only ellipse-specific plugs fit correctly. Here is why other shapes do not work.
Oval tube plugs have a rounder profile with blunt ends. At the wide center of the curve, an oval plug and an ellipse plug may look similar. But at the endpoints, they diverge: the oval plug is too round for the pointed ellipse ends, creating gaps at exactly the points where sealing matters most. Always match the end profile: rounded ends = oval, pointed ends = ellipse.
Round tube plugs are circular and cannot fit an ellipse opening. The difference in axes means a round plug either gaps on the long axis or cannot enter on the short axis. No circular plug works on a non-circular tube.
Rectangular tube plugs have flat sides and squared corners. An ellipse tube has no flat sides and no corners. The rectangular plug cannot conform to any part of the ellipse curve.
Half-oval tube plugs fit D-shaped tubes with one flat side and one curved side. An ellipse tube has no flat side. The half-oval plug cannot enter an ellipse tube because its flat geometry has no corresponding surface inside the tube.
The flat PE head of ellipse tube plugs provides basic floor protection on smooth, hard floors and carpet. Not recommended for rough hard floors like textured tile or stamped concrete, where the PE material wears quickly. PE is smoother and softer than bare metal, adequate for most surfaces without scratching. The ellipse head distributes weight across the full area rather than concentrating it at the sharp pointed metal ends.
On scratch-sensitive floors like engineered hardwood or luxury vinyl, apply a round self-adhesive furniture pad to the plug head for dedicated PA6 protection. Choose a round pad size that covers the ellipse head as completely as possible. On rough hard surfaces like textured tile or stamped concrete, furniture slides with ABS surfaces handle the texture better than PE.
Ellipse tube plugs are designed for any hollow ellipse furniture tube that needs a finished, sealed, protected endpoint. ellipse tubing is a design-forward profile choice found in furniture where a sleeker, more dynamic look than standard oval or round is desired.
Match the plug shape to your tube shape. Every shape uses the same PE construction and press-fit concept.

Oval tubes have a rounder, more uniform curve with blunt ends. Ellipse tubes have a more elongated profile with pointed or tapered ends. The two shapes are similar but not interchangeable. An oval plug will gap at the pointed ends of an ellipse tube. An ellipse plug will bind at the blunt ends of an oval tube. Measure your tube and compare the profile to both shapes. If the ends are pointed or tapered, use ellipse tube plugs. If the ends are rounded and blunt, use oval tube plugs.
Measure the short axis (width) and the long axis (length) of the ellipse opening in millimeters, outside edge to outside edge. Then measure the wall thickness with calipers. You need all three measurements. The two available sizes are 15 × 30 and 20 × 40 mm. Always list the shorter dimension first.
No. A round plug is circular and cannot match the two different radii and pointed ends of an ellipse cross-section. The round plug will not enter the tube at all if sized to the long axis, or it will leave large gaps if sized to the short axis. Shape must match shape.
ellipse tubing is less common than round, square, or rectangular profiles in furniture manufacturing. The 15 × 30 and 20 × 40 mm sizes cover the most frequently used ellipse tubing specifications. For other ellipse sizes, contact Business Solutions for custom production.
Yes. Same PE (polyethylene) construction with flexible internal walls. Same press-fit installation. Same chemical, UV, and moisture resistance. Only the cross-section geometry differs. Ellipse tube plugs have the pointed-end profile that matches ellipse tubing specifically.
