Alemite AL338512-A Check Valve 3/8 Inch Nptf

Product Description

The ALEMITE AL338512-A is a check valve with a 3/8 inch NPTF port, designed to allow one-directional fluid or lubricant flow while preventing backflow in lubrication and fluid-handling systems. Check valves of this type are standard components in grease and oil distribution lines, protecting pumps and fittings from reverse pressure. At 0.16 pounds, the AL338512-A is a compact, lightweight unit suited for tight installation spaces. Licensed plumbers, lubrication technicians, and industrial maintenance professionals typically install and service this type of valve.

This check valve is well-suited for grease distribution systems, centralized lubrication setups, and general fluid-line applications where backflow prevention is required. The 3/8 inch NPTF thread connection is a common size in industrial and commercial lubrication lines, making this valve a straightforward fit in many existing configurations. It is sold individually and is appropriate for both new installations and replacement of worn or failed check valves in service.

• 3/8 inch NPTF port for secure, pressure-rated threaded connections
