EURO Tube Patch 90 mm – Xtra Seal
Vulcanizing inner tube patch | EURO type | Brand: Xtra Seal | Sold as: 1 pc.
The EURO tube patch 90 mm from Xtra Seal is a round patch sitting closer to the top of the EURO round-format range — 24 mm smaller than the largest 114 mm patch, but clearly bigger than the mid-range 70 mm. At this diameter, it handles more extensive punctures in agricultural, industrial, and truck inner tubes where the injury is too large for 70 mm but doesn't necessarily call for the maximum available format. Applied with cold-cure vulcanization, it's built on a slit mylar backing, peeled off right before mounting.
Product Overview – EURO Tube Patch 90 mm 11-690
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 90 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.
When should you choose 90 mm over 70 mm or 114 mm?
The 90 mm format suits damage too extensive for the 70 mm patch but clearly smaller than what the 114 mm format would normally be used for. The difference between 90 mm and 114 mm is 24 mm in diameter — for injuries in that range, the 90 mm lets you match the patch size closer to the actual damage without reaching for the largest available format.
Which cements and sealants work with the 11-690 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.
