Engine Oil Drain Valve

The Fumoto F137N is a large-body F-Series oil drain valve engineered for convenient and mess-free oil changes. It incorporates a long nipple and an LC-10 lever clip, allowing for one-touch operation. This design facilitates clean oil draining without the mess typically associated with traditional drain plugs. Constructed with durable materials, including chrome-plated brass, stainless steel, and forged brass, alongside a fiber gasket, the F137N is built to withstand engine vibrations and extreme temperatures. It features a M12-1.75 thread size, a female iron pipe inlet connection, and an NPT outlet connection, both with a 0.5-inch size. The valve is rated for a maximum operating pressure of 145 PSI and complies with RoHS standards. Installation involves hand-tightening the valve into the oil drain port, ensuring not to cross-thread, followed by final tightening with a crescent wrench on the valve body. The long nipple design is recommended for vehicles with high ground clearance or industrial engines. Some sources suggest it fits most Asian vehicles due to its M12-1.75 thread, while specific fitment for GM 6.6L Duramax (2017-2026) and 3.0L Duramax (2020-2026) Silverado/Sierra models is also noted.
