This \u003cstrong\u003eSteel Inverted Flare Nut\u003c\/strong\u003e distributed by FleetPro Parts \u0026amp; Tires is the \u003cstrong\u003e3\/8in SAE inverted flare\u003c\/strong\u003e nut that clamps a flared tube into its seat on truck and trailer air-brake and air-line connections. A nut that will not pull up - because the threads are chewed, the hex is rounded, or somebody substituted the wrong size - leaves a joint that seeps every time the system charges, and a seeping joint is the slow leak nobody finds until the truck will not build pressure. 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\u003eA Nut That Backs Off Again: The 3\/8in SAE Inverted Flare Nut Advantage\u003c\/h2\u003e\n\n\u003cp\u003eThis nut is \u003cstrong\u003esteel\u003c\/strong\u003e, not brass, and that is the point of the part. Steel takes the wrench without the hex corners deforming, so the nut can be pulled up to a real seat and backed off again at the next repair instead of rounding on the first pass. The \u003cstrong\u003e3\/8in SAE inverted flare\u003c\/strong\u003e form is the standard on heavy-truck air lines: the nut drives the flared tube end into the matching inverted seat and the metal-to-metal cone does the sealing, with no thread sealant, no O-ring and nothing to age out.\u003c\/p\u003e\n\n\u003cp\u003eKeep a few in the box - the nut costs almost nothing and the tube it saves does not.
