Spin-On Adapter Kit (13/ 16-16)

The Spin-On Adapter Kit (13/16-16) by DERALE is a precision oil filter bypass adapter designed for vehicles requiring block-mounted filtration solutions with 13/16-16 in center thread configuration. This adapter kit addresses the need for reliable oil bypass filtration in performance engines, marine applications, and systems where conventional spin-on filter housings are impractical or unavailable. The bypass design allows unfiltered oil to circulate during cold starts or high-flow conditions, protecting engine components while maintaining pressure stability.

Constructed from durable aluminum with a polished finish, this adapter features 1/2 in NPT inlet and outlet ports for seamless integration into existing fuel or lubrication systems. The polished aluminum construction resists corrosion while maintaining a professional appearance in engine bays, and the NPT threading ensures leak-free connections with standard hose fittings. The bypass bypass valve design permits controlled oil circulation, preventing excessive pressure buildup while ensuring optimal filtration when system conditions normalize. At just 0.9 lbs, the compact footprint measures 4.4 x 2.3 x 7.3 inches, accommodating tight engine compartment layouts without compromising performance.

This kit suits builders, restoration specialists, and engine enthusiasts upgrading cooling or lubrication systems on classic cars, street rods, and custom engines where OEM spin-on filter housings don't apply. Installation requires block mounting with the specified 13/16-16 in center thread; ensure your engine block features compatible threading before purchase. The polished aluminum construction makes this adapter ideal for show-quality engine builds while maintaining full functional integrity in high-performance applications. Verify inlet and outlet port compatibility (1/2 in NPT) with your hose diameter and fittings before final assembly.
