Parker BD-LG1018 Push-to-connect Union Fitting 3/16 in

Product Description

The PARKER BD-LG1018 is a push-to-connect union tube fitting designed for tube-to-tube connections in fluid and pneumatic line applications. Constructed from nylon, this union fitting accepts 3/16 inch outside diameter tubing and is rated to 290 psi. Installation requires no tools for tube insertion — the push-to-connect mechanism grips and seals tubing on contact. This fitting is well suited for plumbing, HVAC, and light industrial fluid-transfer runs where a fast, reliable inline union is needed without threaded or compression fittings.

The BD-LG1018 is used in residential and light commercial settings where 3/16 inch OD tubing must be joined inline. Typical applications include condensate drain lines, pneumatic control tubing, and similar low-to-medium pressure fluid circuits. Its nylon construction makes it appropriate for water, air, and compatible non-aggressive fluid service. Technicians working on HVAC equipment, refrigeration accessories, or small-bore pneumatic runs will find this a straightforward drop-in union for existing or new tube runs.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and secure grip

• Compact form factor fits tight equipment enclosures and panel runs

Compatibility

Designed as an OEM-style inline union replacement for systems using 3/16 inch outside diameter push-to-connect tubing in pneumatic or fluid-transfer applications.

Installation Notes

This fitting is installed by trade plumbers, HVAC technicians, and pneumatic system technicians. Before servicing any line, depressurize and isolate the circuit completely. Ensure tubing is cut cleanly and squarely with a tube cutter — ragged cuts can compromise the push-to-connect seal. Verify tubing OD is 3/16 inch before insertion; mismatched tubing will not seal correctly.
