Why choose GMR+ flexi hoses?

Precision welding

We weld each hose using CNC tig technology in a protective atmosphere. The result is strong and clean welds.

We also produce to order

We have common lengths and designs of flexi hoses in stock and can deliver them within a few days. From 10 pieces, we can produce custom-made hoses in atypical lengths, specific colors and with various types of ends.

Checking each hose

We test every product for leaks. No hose leaves production until we are 100% sure of its safety.

Hoses proven over years of operation

GMR+ Flexi Hoses will last you years of safe service. We use stainless steel to make them, which resists corrosion and wear , so you deal with fewer breakdowns. They are also flexible enough to install in hard-to-reach places.

Flexi hose

Amber

Yellow flexible hoses with lower pressure up to 5 kPa . They are used specifically for connecting gas meters with flat seals. They are suitable for places where tightness and safety of the connection are especially important.

For atypical adjustments (AX and BX versions), the output overpressure can be set according to customer requirements.

These parameters are guaranteed on the manufacturer's testing equipment, which meets the requirements of the state testing laboratory, ČSN EN 12279 and TDG 60903.
