Description
The Mishimoto Banjo Fitting with Bolt (MMBB-STBK) is a black anodized, 6061 aluminum fabrication component built with an M20 x 1.5 banjo bolt on one end and a 5/8-in straight hose barb connection on the other, backed by the Mishimoto Lifetime Warranty. CNC-machined for a precise fit, this fitting is purpose-built to give installers clean, exact hose routing where a 90-degree banjo connection is required.
As part of Mishimoto’s Fabrication lineup, this aluminum banjo fitting allows for precise routing of baffled oil catch can hose, converting an M20 x 1.5 banjo bolt connection into a straight, 5/8-in push-on hose barb. Two included dowty oil seals help ensure a properly sealed connection at the banjo bolt interface, and the durable 6061 aluminum construction with a black anodized finish is designed to hold up to the demands of fabrication and catch can plumbing work. Whether you’re building a custom oil catch can setup or need a reliable M20 x 1.5 to 5/8-in hose adapter, this Mishimoto fitting is engineered to make the connection straightforward.
Vehicle Applications
This is a universal Mishimoto Fabrication component defined by its thread and hose sizing rather than a single vehicle platform. Because it features a standard M20 x 1.5 banjo bolt inlet and a 5/8-in straight hose barb outlet, it is intended for use in oil catch can plumbing and similar fabrication applications — such as Mishimoto Baffled Oil Catch Can installations — wherever these matching thread and hose dimensions are required.
