INSTAFLEX pipeline system is designed to meet the highest requirements of diverse building technology applications.

The INSTAFLEX plastic pipeline system is designed to meet the highest requirements of diverse building technology applications – from distribution to the extraction point.

Polybutene, a material specially developed for these applications, offers numerous benefits, from limited expansion force to low weight, space-saving installation, simple processing and high hygiene during operation.

INSTAFLEX is made from Polybutene-1 (Polybutylene, PB-1)

The INSTAFLEX system is made from polybutene - the ideal material for drinking water installations. It has been specially developed for applications in the building technology.

Of all the available full plastic systems, polybutene is subject to the lowest rate of thermal expansion. The material can absorb any expansion in itself. There is no need for expansion pieces or expansion joints.

It also allows the use of commercially available fastenings and fixtures. The result: clean installations which are pleasing to the eye, even if space is tight.

Wide Range of Dimensions
The INSTAFLEX system stands out with a wide range of available sizes (d 16 mm to d 31 5 mm). The same system can be used equally in a single-family detached house, in a hospital or even on board of a luxury ocean liner.

Hygienic Pipe System
Polybutene is corrosion-free and does not release any taste or pollutants. Its smooth surface also prevents limescale deposits.

Quick and Easy Installation
The flexibility of polybutene allows small changes in direction without adapters. This saves additional parts and valuable time during installation on-site. Polybutene remains flexible and easy to handle even at low temperatures.

Cost-effective Prefabrication
Using the Z-dimension method of GF Piping Systems, individual components can be cost-effectively prefabricated in the workshop and quickly installed at the construction site.

Connection Technologies
INSTAFLEX offers the perfect connection technology for every application:
