Description

The Fumoto B158SX is an engine oil drain valve designed for easy oil changes. This valve features a 5/8-18 UNF thread size and a 5mm nipple length with a 3/8" OD nipple diameter.

Installation of the B158SX requires a torque of 221 in-lbs (18 ft-lbs). Its SX series designation indicates a position-adjustable design, allowing for a 360° rotation after installation to optimize oil flow direction and create a smaller profile.
