We carry a complete line of John Guest type tubing and fittings, GA Murdock parts and fittings for Drinking Water Systems and installing water filters. From Valves and shutoff valve adapters to connect to your source water to your Reverse Osmosis System or Carbon Filtration System to specialty fittings like tees and elbows to connect to your refrigerator or ice maker.
We have what you need. There are couplings, reducing couplings, male adapters, Faucet adapters, RO tank valves, in-line ball valves and tubing in 1/4", 3/8" & 1/2" OD LLDPE for all your water treatment needs.
GA Murdock tubing is rated at 230 psi at 70 ° F and is NSF 58. All fittings are made of food grade polypropylene and have dual o-rings for less chance of leaks. Rated at 150 psi at 70 ° F and 60 psi @ 140 ° F.
Easy to use, tubing and fittings are basically tool-less. By making a clean cut using a tubing cutter, just insert the tubing and pull slightly to make sure it is snug. To remove, first relieve the water pressure, press toward fitting on grommet, and pull tubing out.
