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)

Used these for an air pump on a freshwater aquarium system. Good Quality fittings. Used them as reducers for airline tubing going to the tanks.

Works perfectly.

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

Good stuff

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 as intended and well made.

Great and cheap. Work as intended

Great product for a great price.

price great. hard to find these.

Arrived on time. Correct part.
