Protect your AC unit from leaking expensive refrigerant! Some companies are charging close to $200 a pound for R22. One of the frequent culprits is leaking service valves and caps. A is a plastic cap. B is a brass cap with a flare seal. Both of these are well known for leaking. You can go to any supply house and pick up a package of C or D. C is a brass hex cap with an o-ring seal. D is the same but knurled round with an o-ring. Pick up a package and share with family and friends and possibly save a service call!
