Question by: Tommy W on Jan 29, 2026, 3:58 PM
fitting is for -02 hose right? just want to make sure before i order, had the wrong size show up last time
Answer by: Customer Support on Jan 31, 2026, 6:33 AM
the -02 hose designation is right there in the product name, so you're ordering the correct size for that application. The thread end is a 7/16-20 Female JIC 37-degree flare swivel, straight configuration. As long as your hose matches the -02 spec and your port takes a 7/16-20 JIC fitting, you're good to go.
