Quantity

Specifications for Variant SKU: DS4F4-SS316 ZSi-Foster
Brand:	Breco
Series:	DS Series
Shape (Orientation):	Straight
Material(s):	316 Stainless Steel

Interchange:
Compatible with ISO 7241-1, Series B.
Applications:
FHK Series sockets incorporate valves in both socket and plug halves to prevent fluid loss when the socket is disconnected. These sockets are normally referred to as "hydraulic couplings", but they are used extensively with other media where objectionable. The FHK Series sockets are available in ROHS compliant steel and brass.
Features:
Type: FHK, Two-Way Shutoff , Both socket and plug are sealed at disconnect. Operation: Manual - Socket sleeve must be manually retracted to connect and disconnect. Seal Compound: Standard seals are Buna-N. Interchangeability: Standard, most widely used, industrial interchange design. Within each series, only sockets and plugs of the same size will couple to gether. Compatible with ISO 7241-1, Series B. Ordering information: FHK Series couplings are available in ROHS compliant plated steel, brass, and 303 Stainless as standard. Brass couplings have double O-Ring seals (excluding 1/8") and stainless locking balls. Standard seals are Buna-N (Nitrile). Consult factory for optional seals. Vacuum Service: 27" Hg. maximum Rated pressures as defined by ANSI/B93.2-1986 based on 4:1 Safety Factor and non-shock service. NOTE: Only Sockets & Plugs with same prefix digits connect together. Example: 25FS & 25MPB 1 ISO B, Hardened plugs and sleeves constructed from solid bar stock ensures long service life and maximum resistance to damage from hydraulic and mechanical shock. 2 High flow capacity 3 Foster's conical valve with its 360 deg. metal to metal valve stop maintains valve alignment and ensures that poppets open fully every time. 4 Captive valve seal ensures "bubble tight" poppet sealing since seal is positively captured by the metal poppet to minimize seal washout or damage from high fluid velocity. 5 Ball locking mechanism ensures reliable connections every time. Many ball bearings distribute the load while providing alignment and excellent swiveling action to reduce hose torque and prolong hose life. 6 Broad range of metals and seal materials allow the use of most fluids.
