AC Stainless Steel Garter Springs for Spring Lock Couplings
What are AC garter springs?
The AC spring lock coupling is a refrigerant line coupling held together by a garter spring inside a circular cage. Garter springs are circular or “endless springs” formed of helically wound stainless steel wire. When the spring lock coupling is connected together, the flared end of the female fitting slips behind the garter spring inside the cage of the male fitting.
The AC garter spring and cage then prevent the flared end of the female fitting from pulling out of the cage. Always replace the o-rings and garter springs when disconnecting spring lock connections.
