Up for grabs is this SUPCO (Sealed Unit Parts Co) Bullet Piercing Valve For 1/4" 5/16" 3/8" BPV 31. Compact Model Requiring Only 2" Clearance. I have 12 of the SUPCO valves and 4 Johnstone (which is the same valve, made by SUPCO in a Johnstone box) This is a great Saddle valve and an easy way to add a service port to a sealed system, and this beats brazing a valve in line. I've never had any problems with these valves leaking.
(Supco bullet piercing valve for 1/4" 5/16" 3/8" bpv 31 is the responsibility of Eugene Humphrey)
