Description
Coast Spas winter kit fitting with a 3/8-inch barb and 1/4-inch NPSM thread. Winterizing parts like this help open or drain small lines so water can be removed before freezing temperatures arrive. Fits select Coast Spas Elite, Classic, Luxury and Patio models. Check that the thread type on your spa matches NPSM rather than tapered pipe thread before ordering.
