High Performance Hump Hose, 4-Ply Polyester Reinforced

Silicone hump hose with a bulge in the middle of the hose body, is designed to make slight adjustments. For example, it can bend 20 degrees and also compensate for a slight misalignment of the hard pipes. It allows for expansion, movement and extreme vibration between two hard pipes while reducing the possibility of connections pulling off.

Hump hose is reinforced by 4 plies premium polyester fabric. This configuration gives it greater flexibility and strength. Compared with rubber hose, it is superior to withstand a wide range of extreme temperatures and various pressures.
