Warthog Steel JIC 37° Female to Female NPT Adapter
The Warthog Steel JIC 37° Female to Female NPT Adapter joins a 37° JIC (SAE J514) flare connection to a female NPT pipe port in one rugged carbon-steel body. The 37° cone seat makes a metal-to-metal seal with its mating JIC flare, so no thread tape or pipe dope is needed on the flare side, while the female NPT end threads onto standard tapered pipe.
Forged from carbon steel with a zinc-plated finish for corrosion resistance, these adapters are built for high-pressure hydraulic systems, air-compressor plumbing, and fluid-transfer lines. They are dimensionally interchangeable with JIC adapters from Parker, Eaton, Aeroquip, Weatherhead, and Gates.
