EURO Tube Patch 35 mm – Xtra Seal
Vulcanizing inner tube patch | EURO type | Brand: Xtra Seal | Sold as: 1 pc.
The EURO tube patch 35 mm from Xtra Seal is the next size up from the smallest 30 mm variant in the EURO patch line — still meant for small punctures, but with a bit more margin around the damage. It suits slightly larger holes, or two nearby punctures that a single 30 mm patch might not fully cover. Applied with cold-cure vulcanization, it's built on a slit mylar backing, the same as the rest of the line.
Product Overview – EURO Tube Patch 35 mm 11-638
The patch consists of black rubber over a blue tie gum, which bonds it to the repaired tube surface once cured. Thin, even edges keep the patch lying flat against the tube, lowering the risk of the edges lifting over time and making it harder for dirt to collect around the repair.
The slit mylar backing is peeled off right before the patch is applied to the prepared, cement-coated tube surface — until that point, it protects the patch base from dust and accidental contamination.

Frequently Asked Questions
Can the EURO 35 mm patch be used with hot vulcanization?
No — this product is meant for cold-cure vulcanization with Xtra Seal chemical cements. For repairs that call for hot vulcanization or a two-stage method, look to other patches in the Xtra Seal range built for those processes.
Should I choose 30 mm or 35 mm?
It comes down to the size of the injury, not the type of tube — both patches are meant for the same applications. A single, minor nail puncture is usually well served by the 30 mm size. For a slightly larger hole, or two punctures close together, the 35 mm patch is the better choice, giving extra reinforcement margin around the damaged area.
Which cements and sealants work with the 11-638 patch?
The manufacturer recommends Xtra Seal's Standard cement or the blue Super-Blu cement for mounting, followed by Sealiner to protect the edges and buffed surface after the patch is applied.
