EURO Radial Repair Patch 4-Ply 123×250 mm – Aramid Kevlar Cord
Radial tire repair patch | Aramid Kevlar cord | Brand: Xtra Seal | Sold as: 1 pc.
The EURO radial patch 4-ply 123×250 mm with aramid Kevlar cord from Xtra Seal is one of the largest formats in the Xtra Seal range, built for extensive crown-area injuries on radial tires. Combining a large surface area with four layers of aramid cord lets it reinforce the repair zone in cases where smaller patches wouldn't cover the full area at risk of further cracking. It holds up well on tires under heavy, repetitive loads — trucking, construction sites, and agricultural equipment. The patch consists of black rubber over a blue tie gum, on a mylar backing with a slit that makes the protective film easy to remove. It can be applied with cold, hot, or two-stage vulcanization.
Product Overview – EURO 4-Ply Aramid Patch 2-11-AR742
This patch is used on crown-area radial tire repairs where the extent of damage is large enough that standard patch sizes wouldn't fully cover the risk zone. The four layers of aramid cord spread stress across the whole, large surface of the patch and reduce the chance of the repair separating again, even under heavy vehicle use. The fiber ends are constructed to lower the risk of the patch cracking or pulling away from the tire during normal flexing.
The blue tie gum beneath the black rubber is what bonds the patch to the repair area once it's cured. The mylar backing with its pre-cut slit lets you peel the protective layer off right before application, without touching the adhesive surface — at this size, it also makes it easier to position the patch accurately over the damaged area.

Frequently Asked Questions
How does 2-11-AR742 differ from the standard-cord version?
Both come in the same 123×250 mm, 4-ply size, but the cord material differs. 2-11-AR742 uses aramid Kevlar cord, which handles tensile stress and operating loads better than standard polyester cord — this matters more on a patch this large, which carries greater stress across its surface as the tire flexes.
Does a patch this large need different surface prep than smaller sizes?
The process is the same as for smaller patches — Buffer, buffing, vulcanizing cement, mylar removal, roller pressure, Sealiner — but given the 123×250 mm surface area, it's worth buffing the whole zone evenly before applying the patch.
Which cements work with the 2-11-AR742 patch?
For cold cure, Xtra Seal's clear 14-008 or blue Super Blu 14-511 cements both work well. For hot vulcanization, use Black Vulc Cement (4-14-515) gum cement. After mounting, sealing the patch edges and buffed surface with Sealiner (4-14-128A) is recommended.
