One Touch Quick Couplings Hose Socket (Steel)
SH-O-I
One-Hand Operation Quick Coupling, One-Hand Operation Quick Coupler
Stainless One-Way Shutoff Quick Couplings (one touch type) - Hose Socket and Plug, also known as barbed hose socket and plug, - are suitable for use in air compressor, pneumatic tools, automobile, car washing and shipbuilding industry. A shut-off valve in the socket prevents fluid loss in case of disconnection. Moreover, one touch design allows one-hand operation to insert the plug into the socket. Last, the knurled design of or the groove of the quick couplings features anti-slip effect.
There are a few different materials, including SUS316, SUS304, steel, and nylon with glass fiber. Stainless features durability, corrosive resistance, high and low temperature resistance as well as anti-oxidation. Steel features longer life than products on the market. Heat treated plugs enhance the impact resistance; hardness up to HRC45 ~ 50.
One-way shutoff quick coupling type include one touch and tradition. One touch type includes safety, male thread, female thread, and hose series.
Quick Couplings, also known as quick connect and disconnect couplings, quick release couplings, include one-way shutoff, two-way shutoff and two-way shutoff (grease type), one touch quick coupling, straight through type, and camlock type.
