TR415C/TR425C Wide-Bore Snap-In Rubber Tubeless Valves

Where the rest of the TR41-series is built for an 11.5 mm valve hole, the TR415C and TR425C switch to a wider 16.5 mm bore, covering wheels drilled for the larger hole diameter increasingly common on newer rim designs. TR415C runs approximately 42.7 mm long, while TR425C extends to roughly 61.5 mm, giving buyers a short and a long option within the same bore family.

Both are molded as a single piece from oil- and ozone-resistant rubber and snap directly into the rim without additional hardware, keeping installation fast. The wider bore distributes clamping force over a larger contact area, which can help with sealing on rims where the 11.5 mm valves are prone to slight air seepage.

Stocking both lengths together lets a shop cover 16.5 mm-hole wheels regardless of pocket depth, so it is worth keeping TR415C and TR425C side by side with the standard-bore TR41-series parts. Both ship in cartons of ten.
