A variety of coaxial fittings and hose assemblies are available. Coaxial fittings allow the air and oil supplies to be connected simultaneously. Both quick connect/disconnect versions and NPT pipe models are offered.
The coaxial hose assemblies are available with the internal oil capillary tube, including check valve installed in either straight or coiled blue urethane hose. the standard hose lengths are 12, 25 and 50 feet (working length of coiled hose is 9, 18 and 36). Consult Master Pneumatic for other lengths.
Coiled hose assemblies are typically used in applications where the SPL is overhead and the amount of hose on the floor needs to be minimized.
