Specifications for Variant SKU: HS4F4-B Dixon
Series: HS-Series
Shape (Orientation): Straight
Ends Configuration: 1/2in Male ISO-B QD Interchange X 1/2in Female NPTF
Material(s): Brass
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.
