The AP Diving LP 3/8-inch Male Inflator/Regulator Hose Shortener lets you shorten, or repair if damaged, a rubber low-pressure regulator or inflator hose.
The 3/8" UNF First Stage End fitting suits all modern regulator low pressure ports.
The other end fits large bore rubber low-pressure inflator and regulator hoses. Cut the hose to the desired length and fit this shortening adaptor.
Note: Not suitable for use with Miflex and other braided hoses.
