Parker 8Z-C8L-1-BN-B 1/2 Inch Brass Inline Check Valve

Product Description

The PARKER 8Z-C8L-1-BN-B is a 1/2 inch inline check valve designed to allow one-directional fluid flow while preventing backflow in pressurized piping systems. The body is constructed from brass with a stainless steel spring, giving it solid corrosion resistance across a wide range of fluid service applications. Rated at 3,000 WOG (Water, Oil, Gas), this valve handles demanding pressure conditions without issue. Both end connections are compression type, making it a straightforward mechanical fit in copper or compatible tubing runs. Licensed plumbers and HVAC technicians are the primary installers of this style of valve in residential and light commercial systems.

This check valve is suited for inline installation in water, oil, and gas service lines where backflow prevention is required. The compression x compression configuration makes it appropriate for use in copper tubing systems, including potable water supply lines, heating system piping, and refrigerant or fuel service lines where the connection type is compatible. It is commonly installed in tight spaces where a compact inline valve body is preferred over a swing-style check valve.

Key Features

• Brass body construction for corrosion resistance in water, oil, and gas service
• Stainless steel spring provides reliable backflow prevention and long service life
• 3,000 WOG pressure rating handles high-demand system pressures
• Compression x compression end connections for tool-accessible, solder-free installation
• Inline valve orientation fits directly into existing pipe runs without offset fittings
• 1/2 inch pipe size suits common residential and light commercial line sizes

Compatibility

Designed as an OEM-style replacement or new-installation inline check valve for 1/2 inch compression fitting piping systems in plumbing, HVAC, and fluid service applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable IPC or local plumbing codes. Shut off system pressure and depressurize the line before removing or installing the valve. Compression fittings require correct ferrule seating and proper torque to the nut — do not overtighten, as this can deform the ferrule and cause leaks. Verify flow direction marked on the valve body before completing the installation and pressure-test the system after reassembly.
