7241-1 Series B
• Brass construction with stainless steel springs for greater corrosion
resistance and fluid compatibility
• Self-sealing poppet valves provide excellent high and low pressure
sealing
• Standard seal material: Nitrile (NBR)
• Seal options available in PTFE, Neoprene, FKM, EPDM, and Kalrez®
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
