Ham-let 3200799 Inline Check Valve 1/4 Inch 3000 Psi

Product Description

The HAM-LET 3200799 is a 1/4 inch inline check valve designed to allow one-directional fluid flow while preventing backflow in high-pressure systems. Built with a 316 stainless steel body and stainless steel spring, this valve is rated for up to 3,000 psi working pressure and handles temperatures up to 375 degrees F. The Viton seal provides reliable chemical resistance across a broad range of media. With compression x compression end connections, it installs without soldering or threading. This valve is suited for use by licensed plumbers, HVAC technicians, and industrial piping professionals working on demanding fluid or gas control applications.

This inline check valve is appropriate for residential and light commercial plumbing, HVAC, and instrumentation systems where backflow prevention is required on 1/4 inch compression lines. The 316 stainless steel construction and Viton sealing make it a practical choice for corrosive media, high-pressure service, and elevated-temperature environments. It is commonly installed in compressed gas lines, hydraulic circuits, and process piping where system integrity and pressure retention are critical.

Key Features

• 316 stainless steel body and spring for corrosion resistance in demanding service conditions
• 3,000 psi maximum working pressure rating suitable for high-pressure fluid and gas lines
• Viton seal material provides broad chemical compatibility and temperature resistance
• Compression x compression end connections allow tool-accessible installation without soldering
• Low crack pressure of 0.33 psi minimizes flow restriction at low differential pressures
• Rated to 375 degrees F maximum temperature for elevated-temperature service

Compatibility

Designed as an OEM-style inline check valve for 1/4 inch compression fitting installations in high-pressure plumbing, HVAC, and instrumentation piping systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified technician in accordance with applicable codes including the IPC and IFGC where relevant. Isolate and depressurize the line completely before removing any existing valve or fitting. Ensure compression ferrules are properly seated and connections are tightened to fitting manufacturer specifications using appropriate hand tools. Verify flow direction is aligned with the valve arrow or body marking before pressurizing the system.
