Parker PF-00077 Male Swivel Branch Tee 3/8 in Od 1/4 in Mnpt

Product Description

The PARKER PF-00077 is a brass push-to-connect male swivel branch tee fitting designed for pneumatic and fluid-transfer tubing systems. It accepts 3/8-inch OD tubing on the push-to-connect ports and connects to a 1/4-inch male NPT thread on the branch. The swivel design allows the NPT end to rotate during installation, reducing torque transferred to adjacent connections. Rated for 250 psi maximum working pressure and a temperature range of -40 degrees F to 200 degrees F, this fitting is suited for compressed air, DOT-compliant brake-line, and general pneumatic plumbing work. It is installed by licensed plumbers, pneumatic system technicians, and HVAC service professionals.

This fitting is commonly used in commercial and industrial pneumatic systems, mobile equipment air brake circuits, and HVAC refrigerant-free control-line assemblies. The push-to-connect tube ports allow fast, tool-free tube insertion, making it practical for retrofit work and panel builds where access is limited. The 1/4-inch MNPT branch port threads into a tapped manifold, body, or valve block. The overall length of 2.03 inches and 3/4-inch hex size suit standard tubing layouts without requiring modified clearances.

Key Features

• Push-to-connect tube ports accept 3/8-inch OD tubing without ferrules or compression sleeves
• Male swivel branch allows NPT end to rotate during installation, reducing stress on tubing runs
• Brass construction provides corrosion resistance suitable for compressed air and water service
• 250 psi maximum working pressure supports standard commercial pneumatic system requirements
• Operating range of -40 degrees F to 200 degrees F covers most HVAC and mobile equipment environments
• Meets DOT FMVSS571.106, SAE J2494-3, and SAE J844 standards for brake-line and pneumatic tubing applications

Compatibility

Designed as an OEM-style push-to-connect branch tee for pneumatic tubing systems using 3/8-inch OD tubing and 1/4-inch MNPT threaded ports, conforming to DOT FMVSS571.106, SAE J2494-3, and SAE J844 specifications.

Installation Notes

Installation is typically performed by licensed plumbers or pneumatic system technicians. Depressurize and isolate the tubing circuit fully before removing or installing any push-to-connect fittings. Ensure tube ends are cut square, deburred, and clean before insertion to achieve a proper seal. Apply thread sealant to the MNPT branch port per applicable plumbing or pneumatic system codes; do not overtighten threaded connections into aluminum or plastic manifolds.
