PRIMOFIT is a compression fitting made of malleable cast iron, offering full end-load capability. Additionally, it allows for an angular deviation of up to 3° per compression joint. Suitable for the connection of steel pipes, PE pipes, lead pipes and special steel pipes, PRIMOFIT is available with a black or hot-dip galvanized surface. PRIMOFIT is best suited for new installations, pipe repair and pipe work extension as well as the exchange of valves and filters.

Quick installation

PRIMOFIT compression fittings are pre-assembled and ready for installation on the pipe. Dismantling before installation is not required.

Very versatile connection

PRIMOFIT compression fittings are suitable for different media, pipe materials and pipe diameters and can be easily converted and reused by utilizing spare packs.

Easy assembly – Low costs

No special pipe preparation is needed for the assembly of PRIMOFIT compression fittings. No special tools or skills are required and the joint can be loosened without damage.

High-end materials

PRIMOFIT fittings are made of high-graded whiteheart malleable cast iron. In case of a hot-dip galvanized surface, highly pure zinc, suitable for drinking water, is used for the galvanization.

Adapters & Transitions

Adapters and transitions are essential for connecting metal with plastic pipes or even two plastic pipes. This range covers multiple materials and offers reliable connections while offering high flexibility during assembly.

Bends & Elbows

Bends and elbows are essential fittings that easily change the direction of pipes. The extensive range available offers not only multiple materials but also different curvature degrees to easily fit your piping system.

Caps & End Caps

Caps provide a tight seal and stop the flow direction of a piping system. GF Piping System caps are available in different dimensions, different plastic materials and malleable iron to fit all of your needs. Temporary caps ease the pressure testing of an installed pipeline.

Couplers & Sockets

Simplify the pipe installation process with couplers and sockets. Specially designed to slide easily over pipes with no extra equipment required, they are cemented, welded or mechanically connected to create a pressure-tight joint.


Reducers are used for effecting a smooth transition between two pipes or fittings with different dimensions. The wide selection available covers an exceptionally diverse area of applications. They are available in short or long versions and in centric or excentric versions.

Tees, Y-Pieces and Crosses

When creating branch lines, lightweight tee, wye, and cross fittings make installation much easier. These fittings are made from a range of materials and malleable iron and cover multiple dimension possibilities including various reductions on the same fitting.

Clamp Screw Connections

The GF Piping Systems clamp screw connection guarantees a secure, water-pocket-free connection at full flow.

Spare parts

Original, high-quality spares parts for GF Piping Systems systems and products. Spare parts are available throughout the lifecycle of your system and available in an agreed timeframe.
