High strength, spin-on filter

摘要

A high strength filter element housing suitable for high pressure hydraulic applications which require a minimum burst rating in the range of about 1,000 psi is comprised on an internally threaded tubular portion having its ends closed by an externally threaded base and externally threaded cap. The base has a central opening which is threaded so that the filter element housing mounted as a spin-on housing for use with annular filter elements, the base further having spaced central openings around the threaded central opening. In a preferred embodiment, if the base and end cap are permanently fixed to the tubular portion by adhesive sealing material disposed between the threads attaching the base and cap to the tubular portion.
