Air conditioning hose is used for automotive or domestic air conditioning system. It is a textile-reinforced rubber hose with a thick inner liner. It can be single braided with reinforcement layer of rayon or similar textile or it can be a two textile braided layers, separated from each other by a layer of bonded rubber compound. Both types have an outer cover, which is pricked to allow any refrigerant gas that has permeated through the reinforcement layer to escape without causing the hose to blister. It can also be made with a wire-reinforced with an inner liner, a wire reinforcement layer, and an outer layer of heat-resistant textile reinforcement.
Multilayers air conditioning tubing are made of innerlayer of EPDM/ CR/CSM , intermediate layer of NBR/EPDM and outer layer of EPDM. The three compounds were optimised for bonding, physical properties and cure characteristics.

Disc Brake Hydraulic Hose
Brake hydraulic hoses are the flexible hoses that connect the hard lines that run along the body or frame of your vehicle to the brake calipers. Brake hoses are unbique in the fact they are designed and sized properly to move with the suspension as it travels up and down over bumps in the road.
Since brake hoses carry hydraulic fluid as well as transfer pressure to the brake calipers/wheel cylinders it is critical to inspect these hoses regularly for any types of fraying or external cracks. Traditional rubber hoses tend to shrink over time internally restricting the flow of pressure to the brake calipers. Because of this FCP Euro recommends replacing brake hoses in matches pairs to ensure even braking performance at each corner of the axle.
