Connect the right sizes

The nominal fitting size and thread type must match the spa plumbing. Compare both ends before ordering: an NPSM thread is not an indication of an NPT thread.

Compatibility: check before ordering

Compare both dimensions, the thread type, the ends, and the existing installation with your current part. The Cal Spas brand or inclusion in this collection is not enough to confirm fit. The spa model, year, and configuration must match.

Installation and maintenance

Have the fitting's compatibility and sealing method checked. After installation, check for leaks according to the installation procedure.
