ST American type hydraulic quick coupling
Applications: The ST Series are non-valced couplings for applications where maximum flow is required. Their smooth, open bore offers the lowest pressure drop of any quick coupling design and is ideal for applications such as high-pressure water and steam washers, carpet cleaners and mold coolant lines and many other non-valved applications

Specifications:

ST Features:
1.The smooth, open bore with no valving in either half offers minimal pressure drop and allows easy cleaning in applications where the same lines are used for more than one media.
2.ST couplers and nipples are machined from solid bar stock providing the quality coupling that is durable.
3.ST nipples are available in brass and zinc-Plated steel. The ball locking grooves of the steel ST nipples are case hardened for resistance to brinelling where high cycle rates and pressure surges are encountered.
4.The ST is an "interchange" coupling because the dimensionally and functionally can interchange with similar couplings made by other manufactures.
5.Compatible with PARKER ST Series, HANSEN ST Series, FOSTER FST Series.

Performance: Test Fluid:Oil-200SUS,1GPM=3.78L/Min,1PSID=0.0069MPa.
