Bias Tire Patch EURO BN1 55 mm (1-Ply) – Xtra Seal
Diagonal tire repair insert | Type BN1, 1-ply cord | Brand: Xtra Seal | Sold as: 1 pc.
The EURO bias tire patch BN1 55 mm from Xtra Seal is a repair insert with one layer of bias (diagonal) cord, built exclusively for bias-ply tires — both tube-type and tubeless. Unlike radial repair inserts and universal patches without cord, this product has a built-in cord layer running diagonally, matched to the construction of a bias tire. A secondary use sets it apart: the BN1 can also serve as a valve housing for tube valves in truck and agricultural inner tubes. The slit mylar backing is peeled off right before mounting. It works with cold and hot vulcanization.
Product Overview – Bias Tire Patch EURO BN1 55 mm 11-488
The patch consists of black rubber over a blue tie gum, which creates a durable bond with the inner liner surface once cured. The single layer of crosswise bias cord (1-ply designation) reinforces the repair area in a way that's compatible with the tire's own structure. Thin, even edges lower the risk of the patch lifting and make it harder for dirt to collect around the repair.
The BN1 can also be used as a valve housing for the tube valve in truck and agricultural inner tubes — a secondary function that's useful when the original valve housing is damaged. The slit mylar backing is peeled off right before the patch is applied to the prepared, cement-coated inner surface.

Frequently Asked Questions
Can the BN1 bias patch be used on radial tires?
No — the bias cord insert is built for bias-ply tires only. Using it in a radial tire would go against repair technology guidelines, because the bias cord arrangement doesn't match the structure of a radial tire. For radial tires, radial-cord repair inserts should be used.
How is this patch used as a tube valve housing?
In truck and agricultural inner tubes, the valve is held in place through an opening in the tube by a valve housing. When that housing is damaged or needs replacing, the BN1 patch can take on this role — its size and construction are suited to the valve types used in those tubes.
Which cements work with the 11-488 patch?
The manufacturer recommends Xtra Seal Standard cement (14-008) or Super-Blu (14-511) for cold-cure vulcanization. After mounting, sealing the patch edges and buffed surface with Sealiner is recommended.
