These male to male adaptors are suited for adapting oil coolers or tale off plates which have an M22 x 1.5 female port. The adaptors are manufactured from plated steel and all feature a M22 x 1.5 male on one end and various sizes on the other end. These sizes can be chosen from the drop down menu.
The M22 x 1.5 threaded end should be installed using a bonded (doughty) seal. The fittings are available with the seal included, or without if you already have suitable seals.
