Repair unit for radial tyres | Aramid Kevlar cord | Brand: Xtra Seal | Sold as: 1 pc.
EURO radial repair unit 2-ply 70×125 mm with aramid Kevlar cord by Xtra Seal is an advanced repair material for the professional regeneration of radial tyres. The use of aramid fibres provides exceptional resistance to stress, elongation and mechanical damage. Constructed from black rubber bonded to blue active rubber on a scored mylar backing. Compatible with cold vulcanisation, hot vulcanisation and the two-stage method.
Product description – EURO radial repair unit 2-ply aramid 2-11-AR720
Unit 2-11-AR720 is used for crown area repairs in radial tyres where reinforcement with two plies of cord is required. Aramid cord has very high tensile strength, which translates into repair durability and resistance to operating loads. The special construction of the aramid fibre ends reduces the risk of unit cracking and delamination from the tyre.
The black rubber is bonded to blue active rubber, which ensures a strong and durable bond with the prepared tyre surface. The scored mylar backing allows quick and clean removal of the protective layer immediately before installation, without risk of contaminating the bonding surface.
Features and specifications
Aramid fibre with exceptional tensile strength and resistance to mechanical damage – greater durability than standard cord.

Two plies of aramid cord providing reinforcement at the repair site.
Ensures a strong, durable bond with the prepared tyre surface during vulcanisation.
Allows quick and clean removal of the protective layer immediately before installation.
Compatible with chemical cold vulcanisation, hot vulcanisation and the two-stage method.

Frequently asked questions
How does unit 2-11-AR720 differ from standard unit 2-11-720?
Both units measure 70×125 mm and carry the 2-ply designation, but differ in cord type. Unit 2-11-AR720 uses aramid cord (Kevlar), which has higher tensile strength and resistance to mechanical damage than the standard cord in unit 2-11-720. The aramid unit is selected where greater repair durability or higher resistance to operating loads is required.
Does an aramid cord unit require a different installation technique?
No – the installation procedure is identical to standard radial repair units: surface preparation (Buffer, buffing), vulcanizing cement, unit installation, pressing with a roller from the centre outward, Sealiner on the edges and buffed surface. Compatible with the same Xtra Seal cements.
Which cements should be used with unit 2-11-AR720?
For cold vulcanisation, Xtra Seal vulcanizing cements are recommended: clear 14-008 or blue Super Blu 14-511. For hot vulcanisation, Black Vulc Cement (4-14-515) is used. After installing the unit, sealing the edges and buffed surface with Sealiner (4-14-128A) is recommended.
