Quantity

Specifications for Variant SKU: H4F4-SS-BOP Dixon
Series:	H-BOP-Series
Shape (Orientation):	Straight
Ends Configuration:	1/2in Male ISO-B QD Interchange, 1/2in Female NPTF
Material(s):	316 Stainless Steel
Seal Material(s):	Viton/FKM

Compatibility & Interchange:	Danfoss/Eaton/Hansen HKFR-Series DNP HNV-BOP Series Interchangeable to ISO7241 Series B
Construction:	Machined components are manufactured using solid steel bar stock. Stainless steel balls, retaining rings, and springs maximize corrosion resistance and extend service life. Steel components are plated using ROHS Compliant Trivalent Chrome. Steel nipples are hardened to provide heavy duty performance and resist brinneling. Red powder coated coupler sleeve for easy BOP service identification. Individually marked with the BOP series designation. Locking sleeve is standard.
Seal Components:	Blow-out Preventer (BOP) coupling critical seals are severe service FKM. PTFE Anti-Extrusion ring protects main coupling valve seal from dynamic impulse pressure damage. Coupler has redundant O-ring sealing system. Valve seals are crimped in place to maintain integrity during excessive flow conditions and pressurized connection.
Note:	BOP couplings have been fire tested and Lloyd's certified to 1300°F (700°C) in accordance with API 16D.
