The XRP #12 Straight Thread Plug is a precision hydraulic fitting designed for high-pressure fluid systems in marine engines, fuel injection systems, and performance cooling circuits. Built by XRP-XTREME RACING PRODUCTS, this aluminum plug features an o-ring seal and hex head for secure installation and positive removal. The blue anodized finish provides corrosion resistance essential in saltwater environments where standard finishes deteriorate rapidly.
With a #12 AN (dash-12) straight thread port, this fitting integrates into 12 AN hydraulic lines commonly found in marine cooling systems, fuel rails, and transmission coolers. The o-ring design creates a metal-to-metal seal that withstands vibration and thermal cycling without weeping—critical for offshore applications where system integrity directly impacts safety. The hex head geometry accepts standard wrenches for torque-controlled installation, preventing over-tightening that can crack aluminum ports.
This plug suits weekend anglers upgrading cooling systems on center console or cabin boats, as well as serious offshore fishermen and marine mechanics maintaining high-performance engine bays. It's equally applicable to custom fuel system builds, engine swaps, and hydraulic line terminations where a sealed, removable fitting is required. The aluminum construction keeps weight minimal—important in racing and performance boating where every pound matters—while the blue anodize resists salt spray, fuel contacts, and UV exposure far better than bare aluminum.
