1 CN 1DN NPT Male Fittings GE-NPT

The 1CN NPT male pipe fitting is a dual-end hydraulic adapter (metric 24° cone + 1-inch NPT male thread) for high-pressure systems. It connects DIN 2353 metric tubes to NPT ports, with tapered thread/cone seals, and is made of carbon steel/stainless steel. It is similar to Parker's GE-NPT series.

Description

The 1CN NPT male is a specialized pipe fitting engineered to bridge metric and NPT connection systems in high-pressure hydraulic and industrial fluid setups. Featuring a dual-end design—metric 24° cone-end compression fitting on one side and 1-inch National Pipe Taper (NPT) male thread on the other—it enables seamless integration between DIN 2353 standard metric tubes and NPT-compatible components.

Crafted from versatile materials (carbon steel or stainless steel) to suit varying pressure and environmental demands, this fitting ensures robust performance across applications. The NPT male thread leverages its tapered design to form a leak-tight seal, while the metric 24° cone end utilizes a compression or bite-type mechanism for secure tube attachment.

Ideal for high-pressure scenarios such as hydraulic lines, construction equipment, and industrial fluid systems, the 1CN NPT male eliminates compatibility barriers between metric and NPT connections. Its precision-engineered structure balances durability, sealing reliability, and cross-standard adaptability, making it an indispensable component for systems requiring seamless fluid transfer across differing connection protocols. Whether for heavy-duty industrial use or specialized hydraulic setups, this adapter delivers consistent, leak-proof performance to support critical operational efficiency.
