Parker VS271AB-4-4 Compression Male Run Tee Brass

Product Description

The PARKER VS271AB-4-4 is a brass compression tube male run tee designed for fluid and pneumatic line connections in demanding service environments. The fitting uses a compression x MNPT x compression end configuration, allowing technicians to tap into an existing compression tube run while providing a male NPT branch outlet. It is rated to 400 psi maximum working pressure and handles temperatures from -65 degrees F to 250 degrees F. The 1/4-18 NPTF thread standard ensures a pressure-tight, dryseal connection on the NPT port without relying solely on thread sealant. At 0.15 pounds, it is a compact, single-piece brass fitting suited for plumbing, refrigeration, pneumatic, and hydraulic brake line applications where DOT and SAE compliance is required.

This fitting is appropriate for use in mobile equipment, commercial vehicle brake and fluid systems, and stationary pneumatic or hydraulic assemblies. It meets D.O.T. FMVSS571.106 and SAE J246 standards, making it a code-compliant choice for brake tubing connections and related fluid systems. HVAC and refrigeration technicians, plumbers, and fluid power mechanics routinely use this fitting type when branching off a compression tube run with a threaded male port connection. The 0.189-inch inside diameter accommodates the corresponding tube size without flow restriction.

Key Features

• 400 psi maximum working pressure for demanding fluid and pneumatic service
• Operating temperature range of -65 degrees F to 250 degrees F
• Brass construction for corrosion resistance and reliable tube grip
• Meets D.O.T. FMVSS571.106 and SAE J246 standards

Compatibility

Designed as an OEM-style compression tube fitting for fluid, pneumatic, and brake line systems requiring a 1/4-18 NPTF male run tee that conforms to D.O.T. FMVSS571.106 and SAE J246 standards.

Installation Notes

Installation should be performed by a qualified plumber, fluid power mechanic, or HVAC technician. Depressurize and drain the system completely before disassembling any existing tubing connections. Ensure tube ends are cut cleanly and deburred before seating into the compression fittings to prevent leaks. Follow applicable codes such as SAE J246 torque and assembly guidelines and verify the system is leak-free before returning it to service.
