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)

price great. hard to find these.

Great product for a great price.

Arrived on time. Correct part.

Works as intended and well made.

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.

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.

Great and cheap. Work as intended

fits as adverstised

Good stuff

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