Reducing Pipe to Pipe Joint
The Reducing Pipe to Pipe Joint is a stainless steel fitting designed to connect two pipes of different diameters in industrial systems. Ideal for contractors managing fluid or gas lines, this press-fit joint provides a secure, leak-proof transition between pipe sizes without welding or threading. Simply insert each pipe into the joint and press to seal—saving time and labor. Made from corrosion-resistant 304 stainless steel, it’s suitable for a wide range of applications including water, steam, air, and chemicals. Elastomeric seals absorb vibration and thermal expansion, ensuring long-term reliability in demanding environments.
