Midland Industries 20206N 90-deg Union Elbow 4mm Ptc

Product Description

The MIDLAND INDUSTRIES 20206N is a 90-degree union elbow fitting designed for metric pneumatic and fluid control tubing systems. Constructed from nickel-plated brass, this compact fitting accepts 4 mm push-to-connect tubing on both ends, allowing a direction change without tools or ferrules. It is rated for pressures from 0 to 290 psi and temperatures from -4 to 176 degrees F. With a center-to-end dimension of 0.663 inches and a body size of 0.351 inches, it fits into tight spaces on control panels, manifolds, and instrument lines. Plumbers, HVAC technicians, and industrial maintenance professionals install this type of fitting where a compact, reliable 90-degree transition is needed in a metric tubing run.

This fitting is suited for residential and light commercial applications involving compressed air, inert gas, or compatible fluid lines using 4 mm OD metric tubing. It is commonly found in instrumentation panels, pneumatic control circuits, and small-bore fluid distribution systems where a push-to-connect union elbow simplifies routing and allows future disconnection without cutting tubing. Its metric sizing makes it appropriate for equipment of European or OEM origin that specifies 4 mm tubing throughout.

Key Features

• 90-degree union elbow allows direction change on both ends without system disassembly
• 4 mm push-to-connect on both sides - no tools, ferrules, or thread sealant required
• Nickel-plated brass construction resists corrosion in damp or humid service environments
• Rated 0 to 290 psi for use across a broad range of low- to medium-pressure applications
• Operating temperature range of -4 to 176 degrees F covers most indoor control system conditions
• Compact body size of 0.351 inches fits confined panel and manifold installations

Compatibility

Designed as a direct-fit union elbow for systems using 4 mm OD push-to-connect metric tubing in pneumatic or compatible fluid service lines.

Installation Notes

Depressurize and isolate the line fully before disconnecting or installing any push-to-connect fitting. Insert tubing straight and fully into the fitting until it seats to ensure a leak-free connection. To release tubing, depress the collet ring squarely before pulling the tube out - do not twist the tube during removal. Installation should follow applicable pneumatic or fluid system codes and the equipment manufacturer's guidelines.
