EURO Tube Patch 70 mm – Xtra Seal
Vulcanizing inner tube patch | EURO type | Brand: Xtra Seal | Sold as: 1 pc.
The EURO tube patch 70 mm from Xtra Seal is a round patch sitting in the middle of the line between the smaller round formats (up to 52 mm) and the largest round patch in the EURO range (114 mm). At 70 mm in diameter, it provides noticeably more reinforcement margin than the 52 mm size without going straight to the largest available format — making it the natural choice for moderately sized, round or irregular punctures in car, agricultural, and industrial inner tubes. Applied with cold-cure vulcanization, it's built on a slit mylar backing, peeled off right before mounting.
Product Overview – EURO Tube Patch 70 mm 11-679
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 70 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 70 mm over 52 mm or 114 mm?
The 70 mm format suits damage that clearly exceeds the range of the smaller sizes (up to 52 mm) but doesn't yet call for the largest format at 114 mm. In practice, it's the right pick for holes larger than roughly 25–30 mm across, where the smaller sizes wouldn't leave enough margin and the 114 mm would be more patch than the injury needs.
Which cements and sealants work with the 11-679 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.
