One Touch Quick Coupling Female Socket (SUS)
SF-O
One-Hand Operation Quick Coupling, One-Hand Operation Quick Coupler
One Touch single-valve quick coupling, featuring push to connect with one hand operation, facilitates rapid piping connections and disconnections. This coupling is compatible with various components such as Male Plug, Female Plug, Hose Plug, or PU Plug, catering to the diverse needs of machinery, systems, and equipment.
To ensure reliable construction in the field, the outer ring is designed with knurling or grooves that prevent slipping.
One-way shutoff quick coupling type include one touch and tradition. One touch type includes safety, male thread, female thread, and hose series.
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.
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.
