Parker 164PLP-3 Union Tee Fitting 3/16 Inch Od 300 Psi

Product Description

The PARKER 164PLP-3 is a push-to-connect union tee tube fitting designed for tube-to-tube connections in pneumatic and fluid distribution systems. Constructed from nickel-plated brass, it accepts 3/16-inch OD tubing on all three ports and requires no tools to make a secure connection — tubing inserts directly and locks in place. The fitting is rated to 300 psi maximum working pressure and handles temperatures from 0 degrees F to 200 degrees F, making it suitable for a wide range of light industrial, HVAC controls, and instrumentation applications. The black actuator button is made from a flame-resistant material that meets the UL94 V-0 standard. Nitrile o-rings provide the internal sealing contact.

This fitting is used in pneumatic control lines, instrument air tubing, and fluid conveyance systems where a tee branch is needed without compression ferrules or soldering. It is appropriate for residential and light commercial HVAC controls tubing, OEM equipment plumbing, and panel assembly work where 3/16-inch OD soft tubing is routed to multiple components. The push-to-connect design speeds up installation in tight panel spaces or multi-branch tubing runs where traditional fittings would slow assembly.

Key Features

• Push-to-connect design — no tools required for tube insertion and locking
• Nickel-plated brass body resists corrosion in moderate environments
• Rated to 300 psi maximum working pressure
• Operating range from 0 degrees F to 200 degrees F
• Nitrile o-rings provide reliable internal sealing
• UL94 V-0 compliant flame-resistant actuator button

Compatibility

Designed for use with 3/16-inch OD tubing in push-to-connect tube-to-tube configurations. Compatible with common soft tubing materials used in pneumatic and instrumentation plumbing where push-fit fittings of this OD are specified.

Installation Notes

This fitting is typically installed by HVAC technicians, instrument technicians, or OEM assembly technicians working with pneumatic or fluid control lines. Before servicing or replacing fittings in a pressurized system, depressurize the line fully and confirm zero pressure before disconnecting tubing. Ensure tubing ends are cut square and deburred before insertion to achieve a proper seal. Refer to applicable system codes and the equipment manufacturer's specifications for tubing material and routing requirements.
