Gas Flex 1/2" Tubing Pipe KIT 33ft with 2 MALE Fittings Gasflex;

Comes with 1/2' MALE NPT fittings on both ends. (SEE IMAGES) The KIT arrives with the brass connectors hand tightened , they are attached but not tightened or fixed. This is so that before fixing them to the existing network, you can remove them, apply a little pipe dope sealant on the tapered threads , and affix the threaded part to the existing gas network (no pipe dope necessary on the swivel nut or threads), ....then reconnect the pipe and secure tight the swivel nut. Not having the connectors tightened also makes sense though as depending on your application you can feed the hose through 1/2" holes through walls, etc. and once in place, then apply the connectors (which are large nuts). Outside Installation: gasFlex recommends that whenever the pipe is installed outside where it can be exposed to direct sunlight, it shall be covered with conduit to prevent continuous exposure. Inside Installation: Whenever the pipe is installed inside the building , it can be installed exposed to indoor light , or it can also be embedded in concrete, or behind the wall in dry wall systems as needed. Underground Installation The outer PE layer in gasFlex create a shield that makes it resistant against acid, alkaline or salty soil and alloys the system to be buried underground
