John Guest Refrigerator Water Line Check Valve, 1/4 Inch OD - 1/4SCV-US

John Guest Refrigerator Water Line Check Valve, 1/4 Inch OD - 1/4SCV-US

Maintain the specified one-way water flow with this John Guest check valve. This inline check valve allows water to pass in the intended direction while resisting reverse flow. It uses 1/4-inch OD push-fit tubing connections and has a 0.3 PSI cracking pressure.

Compatibility: Compatible refrigerator ice maker and water dispenser supply lines, filtration systems and other potable-water applications.

Includes: One check valve. Tubing and other fittings are separate. This is an individual part, not a complete installation kit.

Fitment / What To Verify: Match tubing OD, valve flow direction and the required check-valve specification. Cracking pressure is the pressure needed to begin opening the valve, not its maximum working-pressure rating. Tubing sizes are outside diameter, not inside diameter.

Confirm tubing size, connection type and application before ordering.

Installation: Use the flow marking to orient the valve; a plain union connector does not provide its one-way function.
