Product Features
European Pressure Equipment Directive
• Meets dimensional requirements to ISO standard
7241-1 Series B
• The coupling that sets the industry standard
• Self-sealing poppet valve design provides excellent high and low
pressure sealing
• Standard seal material: Nitrile (NBR)
• Seal options available in PTFE, Neoprene, FKM, EPDM, and Kalrez®
• Standard body material: Zinc trivalent plated steel with stainless
steel springs, balls and retaining rings.
• PTFE back up rings in sockets (females)
Couplings with nominal diameters up to and including 25 mm
are designed and manufactured under Article 4.3 of the European Pressure Equipment Directive 2014/68/EU. Couplings
with nominal diameters greater than 25 mm are designed and
manufactured in accordance with stipulations of Module A of the
