1/2 in to 1/4 in Adapter Pack
This Loc-Line 51821 adapter connects 1/2 inch hose to 1/4 inch fittings in plumbing and coolant systems. Made from acetal copolymer for chemical resistance and durability. Supplied as a pack of two for spares or dual connections. Ideal for technicians adapting existing hose lines to smaller ports.
Replaces mismatched fittings
Use these adapters when joining 1/2 inch ID hose to 1/4 inch components without replacing the whole assembly. The jump is worth it when a reducer is cheaper and faster than re-plumbing. Not for buyers who need a straight coupler or a different thread standard.

Questions about this item
What hose inside diameter does the Loc-Line 51821 adapter accept?
The adapter fits a hose with a 1/2 in. inside diameter and reduces it to a 1/4 in. connection for the drain system.
How do I install the Loc-Line 51821 adapter without causing leaks?
Push the hose fully over the 1/2 in. barb until it seats against the body; the step most people miss is not seating it completely, which leaves a leak path.
