Parker 6Z-C6L-1-BN-B Check Valve 3/8 in Compression Brass

Product Description

The PARKER 6Z-C6L-1-BN-B is a 3/8-inch inline check valve designed for compression-to-compression installations in fluid and gas distribution systems. The brass body provides corrosion resistance suitable for water, oil, and gas service, while the stainless steel spring ensures consistent cracking pressure and long service life. Rated at 3,000 WOG (Water, Oil, Gas), this valve handles high-pressure applications common in commercial and industrial plumbing, pneumatic, and hydraulic lines. Plumbers, pipefitters, and HVAC technicians install this valve to prevent backflow in pressurized systems where flow direction must be controlled reliably.

This check valve is suited for inline installation in 3/8-inch compression-fitting systems. Typical applications include refrigeration and HVAC refrigerant lines, compressed air distribution, hydraulic circuits, and general plumbing service where backflow prevention is required. The compression x compression end connections allow tool-assisted installation without soldering or threading, making it a practical choice for service work in tight spaces or retrofit applications.

Key Features

• 3,000 WOG pressure rating supports demanding water, oil, and gas service environments
• Brass body construction resists corrosion in fluid and gas applications
• Stainless steel spring provides reliable cracking performance and long cycle life
• Compression x compression end connections eliminate the need for soldering or threading
• Inline valve orientation simplifies installation in straight pipe runs
• Compact design at 0.4 pounds for use in confined installations

Compatibility

Designed as an OEM-style inline check valve for 3/8-inch compression fitting systems in HVAC, plumbing, pneumatic, and hydraulic applications.

Installation Notes

This valve is installed by a licensed plumber, pipefitter, or HVAC technician. Shut off and depressurize the system completely before removing any existing components or installing this valve. Compression fittings require proper tube preparation and ferrule seating to achieve a leak-free connection. Verify flow-direction markings on the valve body before final installation and confirm the completed assembly holds pressure before returning the system to service.
