This very popular Canadian Gurdy control valve was made for many years equipped with 1/2" NPT Ports, which inevitably would start leaking due to the pipe-thread style. The valves were also available in a 'left-handed' valve, and a right-handed' Valve, which posed some problems when trying to match/mount and plumb the necessary hoses to the valve. Both of these problems have now been addressed and have been eliminated!
If you need to replace only one valve, simply buy one valve and plug the Side-port you're not going to use.
Kolstrand's part number for these valves is part No. AKPNGHP-41-CA-ORB, and fits Kolstrand's brass and nylon multi-spooled Gurdys, and comes with new O-rings
Please note that the older-style 1/2" NPT ported valves are no longer available!
