PUSH TO CONNECT: CONNECT UNDER PRESSURE COUPLING

SafeWay’s S70 Series offers unique internal valving, combined with SafeWay’s two-way sleeve feature, allowing one-hand connection under full system pressure. The body (coupling) half can be mated to either a ball valve or poppet valve ISO male tip (nipple). The S70 Series is used primarily with agricultural equipment. It is original equipment on full size tractors and front-end loaders. Use when connection and disconnection under pressure, without the use of tools, is desirable.

REQUEST INFORMATION ON PUSH TO CONNECT: CONNECT UNDER PRESSURE COUPLINGS

	1/2" body size couplers and male tips meet ISO 5675, S.A.E. and ASAE interchangeability and performance requirements.
	Available in 1/2" body size, in a variety of thread sizes and styles.
	After hook-up, the hydraulic circuit automatically opens when the hydraulic system is operated.
	Two-way sleeve design allows one-hand hook-up and break-away when clamp or bulkhead mounted. Clamp and snap-rings available.
	Easy one-hand connection to a clamp or bulkhead mounted coupler while male tip and female body half are both — or either — under pressure.

	All poppet versions are 100% leak tested.
	Critical parts are hardened for long service life.
	SafeWay began a running change from zinc and yellow chromate plating (gold appearance) to ROHS compliant plating (silver appearance) in 2007.
	May be used with either an open center or closed center hydraulic system that has a control valve.
	Interchangeable half-for-half with the Parker/Pioneer 8200 Series.
	Method of obtaining and presenting performance data conforms to ANSI/(NFPA)T3.20.2.R2, Hydraulic fluid power - Quick-action couplings - Test methods.
