CD2245 – BRASS CAP (1/4″, 6/PKG)

Brass flare caps seal refrigerant service valve ports when they’re not being used. If a cap is missing or the O-ring is worn, you’ll get a slow refrigerant leak over time. These 1/4″ caps come with neoprene O-rings for a tight seal. Keep a pack on hand — they go missing all the time.

What size are HVAC service fittings?

1/4 inch flare is the standard service port on residential equipment. Most of the adaptors and caps here step between 1/4 inch and other sizes so you can connect gauges, a recovery machine or a vacuum pump.

Why do I need a left-hand thread adaptor?

A2L refrigerants - R-454B and R-32 - use LEFT-HAND (reverse) threaded cylinder connections. It is a deliberate keying change so A2L equipment cannot be cross-connected to older refrigerant. Without the adaptor a standard hose simply will not start on the tank.

Does the cap actually matter?

Yes. The cap is the primary seal on a service port, not the Schrader core. The core is a valve; the cap with its gasket is what holds refrigerant in over years. A missing cap is a slow leak you will not find with a sniffer for a long time.

What is a core removal tool for?

Taking the Schrader core out so you can pull a proper vacuum through a full-bore path instead of through a tiny valve. On anything bigger than a small system it is the difference between a real vacuum and a long afternoon.

Male or female - how do I tell?

Male threads are on the outside of the fitting, female on the inside. The listings here spell out each end, for example 1/4" male to 1/2" female, so you can match what you already have.
