Brass Grease Fittings

Product Description

These are designed for use in untapped holes (thus saving cost of tapping). When screwed in, they are meant to cut and form a thread in the untapped hole, resulting in a leak proof fitment.

These may also be pressed straight into untapped holes. Worn out or damaged thread forming fittings can be replaced with standard threaded fittings, or by another thread forming thread fitting.
