Midland Industries 20170C Female Bulkhead 1/4 in Ptc X 1/8 in Npt

Product Description

The MIDLAND INDUSTRIES 20170C is a composite push-to-connect female bulkhead fitting designed to pass tubing through a panel or enclosure wall while providing a secure, leak-free connection on both sides. The inlet accepts 1/4-inch push-to-connect tubing for fast, tool-free tube insertion, and the outlet threads into a 1/8-27 female NPT port. Built from composite material, the fitting is rated for 150 psi working pressure and a temperature range of 32 degrees F to 140 degrees F. It is suited for pneumatic control lines and low-pressure fluid circuits in light industrial, HVAC, and plumbing panel applications.

This bulkhead fitting is used wherever a compressed air or fluid line must pass cleanly through a bulkhead, enclosure wall, or mounting panel. The composite body keeps weight low and offers adequate chemical resistance for most air and water service applications. The push-to-connect side speeds up field assembly by eliminating the need for compression ferrules or soldering, making it a common choice for HVAC controls panels, pneumatic actuator circuits, and similar installations requiring neat, panel-mounted tubing runs.

Key Features

• 1/4-inch push-to-connect inlet for tool-free tubing insertion and removal
• 1/8-27 female NPT thread on the outlet side for standard port connections
• 150 psi maximum working pressure rating
• Operating temperature range of 32 degrees F to 140 degrees F
• Composite body construction reduces weight and suits most air and water service environments
• Bulkhead design mounts through panels to organize and secure tubing runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1/4-inch outside diameter push-to-connect tubing and 1/8-27 NPT threaded ports used in light industrial pneumatic and low-pressure fluid systems.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or instrumentation technicians working with pneumatic control circuits. Depressurize and isolate the system completely before installing or removing any fitting. The NPT thread side should be sealed with thread sealant tape or compound rated for the service medium; hand-tighten first, then snug with a wrench to avoid cracking the composite body. Push-to-connect tubing must be cut squarely and deburred before insertion to ensure a proper seal.
