Midland Industries 20630N Straight Male Adapter 4mm Ptc

Product Description

The MIDLAND INDUSTRIES 20630N is a straight male adapter fitting designed to transition between a 4 mm push-to-connect port and a 1/8-inch male global thread connection. Constructed from nickel-plated brass, this compact metric connector is built for pneumatic tubing systems where a secure, leak-resistant joint is required without the use of tools on the push-to-connect side. It carries a rated working pressure of 290 psi and operates across a temperature range of -4 to 176 degrees F. The fitting measures 0.702 inches in length with a 0.429-inch hex profile, making it suitable for installations in tight spaces. Pneumatic system technicians and plumbing professionals commonly install this type of adapter.

This fitting is used in pneumatic control systems, automation equipment, and compressed-air plumbing applications where metric tubing must connect to a standard global-threaded port. The 4 mm push-to-connect end accepts metric tubing with a simple insertion, while the 1/8-inch male global thread end engages a corresponding female-threaded port. It is appropriate for both light industrial and commercial service environments that require nickel-plated brass fittings for corrosion resistance and clean appearance.

Key Features

• 4 mm push-to-connect inlet accepts metric tubing without additional tooling
• 1/8-inch male global thread outlet for compatibility with standard threaded ports
• Nickel-plated brass construction for corrosion resistance
• 290 psi maximum working pressure
• Rated for -4 to 176 degrees F operating temperature range
• Compact 0.702-inch length suits confined installation spaces

Compatibility

Designed as an OEM-style replacement or new-install straight male adapter for pneumatic and compressed-air systems utilizing 4 mm metric push-to-connect tubing and 1/8-inch global-threaded ports.

Installation Notes

Installation is performed by qualified pneumatic or plumbing technicians. Depressurize and isolate the air or fluid circuit completely before removing or installing any fitting. Apply thread sealant appropriate for the system medium to the male global thread end before engaging the mating port. Do not overtighten the threaded connection; use the hex profile with a wrench rather than gripping the fitting body directly.
