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)

Great and cheap. Work as intended

Works perfectly.

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.

Arrived on time. Correct part.

Works as intended and well made.

fits as adverstised

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.

Good stuff

Great product for a great price.

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