Press-fit fittings represent a modern, flame-free method for joining pipes that ensures a secure, fast, and reliable connection. This technology utilizes a specialized pressing tool to mechanically deform the fitting around a pipe, creating a permanent mechanical bond. Integrated within each fitting is a high-quality elastomeric O-ring (typically EPDM or HNBR) that, when compressed, forms a durable, watertight, and gas-tight seal. Suitable for copper, stainless steel, carbon steel, and PEX, press-fit systems eliminate the need for soldering, welding, or threading, drastically reducing installation time and eliminating fire hazards. This makes them an exceptionally safe and efficient choice for potable water, gas, hydronic heating, and industrial applications.
