LTWFITTING Bar Production Stainless Steel 316 Barb Splicer Mender 1/2 Hose ID x 3/8 Hose ID Fitting Air Water Fuel Boat (Pack of 5)

Worked exactly how I needed (to combine two different fuel line sizes).

These are super high quality and made from stainless. What more could you want?

price great. hard to find these.

good quality and safe for use in aquariums applications. Also very nice because they work and come in this unusual size...however if you’re anything like me you find that you need to convert between the 1/2 ID output tubing of canister filters to 5/8 ID quite often.

Works perfectly.

Great product for a great price.

Good stuff

fits as adverstised

Great and cheap. Work as intended
