Parker A8TCB8 Push-to-connect Tube to Barb Connector

Product Description

The PARKER A8TCB8 is a push-to-connect tube to barb connector designed for quick, tool-free tubing connections in fluid and pneumatic systems. Molded from polyoxymethylene (POM), a rigid engineering thermoplastic, the fitting accepts 1/2 inch OD tubing on the push-to-connect end and transitions to a barbed outlet for secure hose attachment. The EPDM O-ring provides a reliable seal against moisture and a broad range of fluids. Rated to 250 psi, this fitting is suited for moderate-pressure plumbing, irrigation, water treatment, and HVAC condensate or fluid-transfer lines. HVAC technicians, plumbers, and fluid-system installers use it where a fast, repeatable connection is needed without threading or soldering.

The A8TCB8 is used in residential and light commercial applications where 1/2 inch OD tubing must connect to a barbed hose or fitting. Typical scenarios include HVAC condensate drain lines, water treatment equipment, RO systems, and low-pressure fluid transfer assemblies. The push-to-connect mechanism allows rapid field installation or replacement, reducing labor time on service calls. The gray POM body resists chemical exposure common in water handling and HVAC environments.

Key Features

• Push-to-connect inlet accepts 1/2 inch OD tubing without tools
• Barbed outlet provides a secure grip on flexible hose or tubing
• Polyoxymethylene (POM) body offers rigidity and chemical resistance
• EPDM O-ring seals against water and common HVAC fluids
• Rated to 250 psi for use in moderate-pressure systems
• Compact form factor at approximately 1 inch in length

Compatibility

Designed as an OEM-style push-to-connect replacement fitting for systems using 1/2 inch OD tubing with barbed hose connections in fluid transfer, HVAC, and water treatment applications.

Installation Notes

Installation is performed by HVAC technicians, plumbers, or fluid-system mechanics. Before servicing, shut off system pressure and relieve any residual line pressure. Ensure tubing end is cut square and deburred before inserting into the push-to-connect end to achieve a full, leak-free seat. Verify the barbed end connection is secured with an appropriate clamp or retainer per applicable plumbing or mechanical codes.
