Stainless Steel
Grooved Fittings
Fast, safe, and reliable grooved connection solutions from DN50 to DN400 (2"-16"). Engineered for industrial, commercial, and residential piping systems worldwide.

PiPress Grooved Connection System
The PiPress grooved connection system delivers a fast, tool-free alternative to welding and flanging. Our stainless steel grooved fittings are engineered for demanding fluid and gas transport across a wide range of industries.

Grooved Couplings
Rigid and flexible grooved couplings designed for fast, secure pipe connections in DN50-DN400 (2"-16") sizes. No welding required.

Grooved Fittings
Elbows, tees, reducers, caps, and crosses -- a full range of stainless steel grooved fittings to complete any piping layout.
Valves & Accessories
Grooved butterfly valves, check valves, strainers, and mechanical tees to build complete, integrated piping systems.
Engineered for Speed & Reliability
Fast Installation
Grooved connections eliminate welding and flanging. Significantly reduce installation time and labor costs on site.
Superior Corrosion Resistance
Premium 304/316L stainless steel construction ensures long service life in aggressive media and harsh environments.
Flexible & Rigid Options
Choose between flexible couplings (absorb vibration and thermal movement) or rigid couplings (act like a fixed joint) for your application.
Easy Maintenance & Disassembly
Grooved systems can be disassembled and reassembled quickly without cutting pipe, reducing downtime during maintenance.
Cost-Effective Solution
Lower installation labor, reduced equipment requirements, and minimal maintenance translate to significant total cost savings.
