A high quality braided Kevlar coated microbore hose with a working pressure of 500bar.
 
These hoses are 500mm (50cm) long and have 100mm of heavy duty anti-kink spring at each end, this prevents the hose from cracking or being damaged during everyday use. The hoses have 1/8BSP threaded female socket connectors at each end - this enables the fitment of a wide variety of PCP rifle/pistol fill probes or 1/8BSP male threaded quick couplers.
 
Inside the female threaded ends, the microbore tubing terminates with a conical (cone shaped) steel end. This eliminates the need to use ptfe tape in the joints, although ptfe can be used as well if you prefer that method.
