It is sized for \u003cstrong\u003e1\/2in NPT\u003c\/strong\u003e pipe connections - the bigger bosses on reservoirs, supply manifolds and valve bodies where a wet tank drain, a governor line or an auxiliary circuit used to live. A half-inch port left open or badly capped does not weep, it dumps: the compressor never catches up, the tanks will not build, and the truck is out of service until somebody finds it. Supplied under the Automann brand at Fleet Standard grade, we stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.\u003c\/p\u003e\n\n\u003ch2\u003eBig Ports, Sealed Tight: The 1\/2in Brass Plug Advantage\u003c\/h2\u003e\n\n\u003cp\u003eThis is \u003cstrong\u003estandard NPT pipe connection hardware\u003c\/strong\u003e for truck and trailer air-brake and air-accessory plumbing. The \u003cstrong\u003e1\/2in NPT\u003c\/strong\u003e thread is tapered, so it tightens progressively as it is driven and seals on the thread flanks - the larger the port, the more that matters, because a big straight-thread substitute simply cannot hold that surface area of pressure.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003ebrass\u003c\/strong\u003e body resists the condensate, compressor oil carryover and road chemicals that circulate through a heavy-duty air system, and it will not corrode itself permanently into a cast or aluminium boss the way plated steel does. The hex head gives a wrench or socket a full grip, which is what you want on a fitting this size going into an awkward reservoir position. This plug also carries forward the older Automann \u003cstrong\u003e177.9039\u003c\/strong\u003e reference for shops working from earlier parts lists.\u003c\/p\u003e\n\n\u003cp\u003eAt FleetPro Parts \u0026amp; Tires, we know a plug is not glamorous until the truck will not build air.
