The Rhino Full Nipple fittings are an MPT fitting and allow for NPT connection both inside and outside the tank. Each fitting is produced with Precision Tooling, which guarantees 100% accuracy. Strict ISO 9001 quality control standards are enforced and put into practice on all procedures during the manufacturing process. Rhino fittings have oversized 1/2" diameter studs and come standard with die cut XLPE close cell foam gaskets.
You MUST use an anti-seize compound on the threads prior to assembly.
