  • Machined components are manufactured using solid steel bar stock
  • Stainless steel retaining rings and springs maximize corrosion resistance and extend service life
  • Steel componentry is plated using ROHS Compliant Zinc Nickel for superior corrosion resistance
  • Valve stems have molded Acetal seals, with a temperature range of -65°F to +212°F (-54°C to +100°C)
  • Ancillary coupler seals are Nitrile (Nitrile Rubber), with a temperature range of -40°F to +250°F (-40°C to +121°C)
  • TPC-ET Anti-Extrusion ring protects main coupling valve seal from dynamic impulse pressure damage
  • Two-stage valving to protect critical sealing components during pressurized connection & disconnection
  • Posi-Lock valve system secures valving during surge-flow conditions to prevent high-velocity damage
  • No-spill, flush face valve minimizes air inclusion during connection and spillage during disconnection
  • Threaded design eliminates premature wear or brinelling commonly found with locking ball designs when subjected to high impulse pressures
  • Fully interchangeable with Stucchi VEP-P/VEP-HD Series, DNP PST4/FSI Series, Voswinkel FT Series, Parker FET-Series, and Holmbury HFT Series
