Brass Cap for 3/8" SAE Connections

These brass caps seal 3/8 inch SAE ports on copper fittings. Each cap includes a rubber O-ring gasket for a leak-tight fit. The pack contains three caps for multiple service points. They suit HVAC technicians and installers closing off refrigerant lines during service or storage.

Ready to install on copper fittings

No tools or sealants are required beyond standard wrench tightening. The brass construction resists corrosion in refrigerant environments. The caps free up open ports that would otherwise leak or collect debris. Buyers needing metric threads or larger SAE sizes will need different caps.

Questions about this item

Will the brass threads on the 3/8" SAE caps withstand repeated tightening on copper fittings without stripping?

The caps are made from solid brass, which resists galling and thread deformation during repeated installation and removal on compatible copper fittings.

Do the rubber O-ring gaskets maintain a seal after prolonged exposure to refrigerant oils and temperature cycles?

The included rubber O-rings are designed for HVAC service and retain elasticity through normal refrigerant oil contact and system temperature swings.
