IMPA: 734313

Stainless Steel Flareless Male Connector 12mm PT3/8 (IMPA 734313)

This stainless steel flareless male connector is designed for high-pressure and extreme temperature applications in marine and industrial systems. Made from durable SUS316 stainless steel, it provides excellent corrosion resistance and reliability in demanding environments such as vacuum lines, gas analyzer tubing, and hydraulic circuits.

The connector features a 12mm tube outer diameter with PT3/8 threads conforming to JIS PT (tapered pipe thread) and JIS PF standards. It is rated for a working pressure of 210 Kgf/cm² and a test pressure of 850 Kgf/cm², ensuring safe operation under high stress. The flareless design eliminates the need for flaring tools, simplifying installation and reducing leak points.

Ideal for ship chandlers and marine engineers, this fitting is suitable for use with stainless steel tubing in fuel, lubricating oil, and hydraulic systems. Its robust construction and precision engineering make it a reliable choice for critical fluid handling applications.

Frequently Asked Questions

What is a flareless male connector?

A flareless male connector uses a ferrule to grip the tube without requiring the tube end to be flared. This design simplifies installation and reduces the risk of leaks in high-pressure systems.

What is the working pressure of this connector?

The working pressure is 210 Kgf/cm² (approximately 20.6 MPa / 2990 psi). The test pressure is 850 Kgf/cm².

What types of tubing can I use with this fitting?

This connector is designed for stainless steel tubing with an outer diameter of 12 mm. For best results, use tubing of the same material and hardness.

Is this fitting suitable for seawater or marine environments?

Yes, the SUS316 stainless steel construction offers excellent corrosion resistance, making it suitable for marine applications including fuel, lubricating oil, and hydraulic systems.
