Hydraulic Coupling: HS-Series ISO-B Steam Interchange Plug (Female Threads)

Designed exclusively for steam applications.

Quantity

Specifications for Variant SKU: HS4F4-S Dixon
Series:	HS-Series
Shape (Orientation):	Straight
Ends Configuration:	1/2in Male ISO-B QD Interchange, 1/2in Female NPTF
Material(s):	303 Stainless Steel

Compatibility & Interchange:	Interchangeable to ISO7241 Series 'B' Parker 60-Series Steam Couplings
Construction:	Machined components are manufactured using solid steel, brass, or 303 stainless steel bar stock. Stainless steel balls, retaining rings, and springs maximize corrosion resistance and extend service life. Steel componentry is plated using ROHS-compliant trivalent chrome. Steel plugs are hardened to provide heavy-duty performance and resist brinelling. All couplers have a steel steam-sleeve as standard.
Seal Components:	EPDM steam-grade seals are standard, providing a temperature range of -70°F to 400°F (-57°C to 204°C). Couplers have a redundant O-ring sealing system (dual O-rings with PTFE back-up). Valve seals are crimped in place to maintain integrity during excessive flow conditions.
Note:	Maximum working pressure has been calculated using saturated steam at 382°F (194°C) for general purpose continuous steam service. WARNING: Do not disconnect steam couplings while under pressure. Maximum operating temperature for steam service couplings is 382°F (194°C), with an intermittent maximum temperature of 400°F (204°C). Be sure to use safety chains, or equivalent means, to prevent the line from thrashing around in a case where the coupling becomes disconnected.
Additional Information:	For a selection guide, cross reference tables, safety info, fluid compatibility, and other general info, please see: Dixon Valve Quick Disconnect Guide.PDF
