Exposed bolt threads snagging fabric? Chair legs scratching your hardwood floors? These white round silicone rubber end caps slip over tubes, screw tips, and pipe ends without tools — giving you instant protection and a clean finish that stays put.
Made from elastic, non-toxic silicone rubber, each cap is available in inner diameters from 3mm to 157.5mm (approximately 0.12 in to 6.2 in), with wall thickness that grips firmly without cracking or drying out over time.
Ideal for chair leg floor protection, exposed screw thread covers, walker tube feet, open pipe end seals, and DIY furniture builds — wherever a snug, flexible cap is needed to protect surfaces or people.
Protect hardwood, laminate, and tile floors from chair leg scratches. Slip caps onto dining chairs, stools, and table feet for quiet, scratch-free movement.
Cover exposed bolt and screw tips on shelving, furniture builds, and workshop fixtures. Prevents snagged clothing, skin cuts, and rust starting on thread tips.
Replace worn walker, cane, and crutch feet with silicone caps that grip floors firmly and absorb impact — available in the exact tube diameter you need.
Seal open pipe ends, protect threaded fittings, and cap electrical terminals in environments ranging from cold storage to high-heat equipment rooms.

Measure the outer diameter of the tube, chair leg, or screw tip you want to cap. Choose an end cap with an inner diameter that is slightly smaller — typically 0.5mm to 1mm less than your measured outer diameter. The silicone will stretch to create a firm, slip-resistant grip. If you are between sizes, size down for a tighter fit.
Yes. The elastic silicone grips firmly around the tube or leg. For best retention, select a cap with an inner diameter slightly smaller than the leg's outer diameter. On smooth metal or plastic legs, a drop of rubbing alcohol during installation helps the cap seat fully — once dry, it locks in place and resists daily movement.
Yes. These caps are rated for continuous use up to 250°C (482°F), making them suitable for covering bolts on ovens, sealing hot water pipe ends, or protecting threads on heated equipment. They also remain flexible at -40°C, so they work in cold storage or outdoor winter applications without cracking.
Absolutely — this is one of their most common uses. Slip a cap over any exposed screw or bolt tip to cover sharp threads, prevent snagged clothing, and stop rust from forming on the exposed end. The silicone also provides electrical insulation, making these useful for covering terminal bolts in low-voltage applications.
For sizes above approximately 30mm, apply a small amount of soapy water, rubbing alcohol, or light oil to the tube end before sliding the cap on. This lubricates the surface temporarily. Once the liquid evaporates — typically within a few minutes — the silicone grips the tube firmly and will not slide off under normal use.
Wipe with a damp cloth and mild dish soap for routine cleaning. For heavier grime, soak in warm soapy water for a few minutes, then rinse thoroughly and air dry. Avoid abrasive scrubbers or harsh solvents, which can degrade the silicone surface over time. The non-porous material resists staining and dries quickly.
Yes — simply add each size as a separate item to your cart. Each listing lets you select the exact inner diameter and quantity you need. If you require a custom assortment of multiple sizes bundled together, contact us and we can discuss options based on your project requirements.
