Bulk pack of 50 brass flare caps
This pack contains 50 brass valve caps designed for 1/4 inch flare fittings. They are intended for HVAC technicians, plumbers and maintenance teams who need a large quantity of replacement caps for refrigerant lines and copper pipe installations. The bulk format suits workshops and factories that service multiple systems.
7/16-20 UNF thread with neoprene O-ring
Each cap uses a 7/16-20 UNF thread to match standard 1/4 inch flare connections on copper pipe. An internal neoprene O-ring provides the primary seal, preventing refrigerant or fluid leaks during service, testing or long-term closure. The thread specification is the critical detail for confirming compatibility with existing flare fittings.
Brass construction resists corrosion and deformation
The solid brass body withstands the temperature and pressure cycles found in HVAC and refrigeration work without cracking or stripping. Neoprene seals remain flexible across typical operating ranges, maintaining a tight seal without extruding. No torque values or pressure ratings are supplied, so installers should follow standard trade practice for flare cap tightening.
