Welcome to OUMEIJIA CASTING
Air hose couplings are recommended for use on air lines for virtually
any type of pneumatic equipment. The maximum recommended
working pressure for air hose couplings is 150 PSI or less at ambient
temperature (70° F).
Air hose couplings have a universal head which is identical for all parts
(hose ends, male BSPT and female BSPT) within the 1/4" to 1" range.
This enables any two fittings (within that range) to be directly
connected regardless of hose shank or threaded size.This enables any
of the Air hose couplings with ferrule couplings to connect directly
to any other Air King coupling within the1/4"-1" range. The ferrule
comes attached to the fitting for easy installation.
