So far, the sole priority of competitive products has been to meet the standards. For us, that’s not enough, because we know from over 150 years of experience what really matters in practice.
4-ply standard models only satisfy the required standards by using a huge amount of extra material.
The result is a massive, immovable hose that can’t fit in the hose basket without getting damaged. Equipped like this, a firefighter’s heroic deeds are literally very heavy duty indeed.
With GH hoses, it’s different – and we have the proof!
The hose is designed to give the weft thread the best possible protection against damage. If the weft thread suffers any damage at all, the hose quickly becomes unfit for purpose. Seen from the outside, the weft thread is largely concealed by the GH 4Z weave system
Image on right: In the TITAN COMBAT NEON (above), the white weft thread can barely be seen, whereas the orange weft thread of the conventionally designed TITAN 3F NEON (below) is plain to see
Unlike competitive products, Gollmer & Hummel satisfies LS2 and LS3 requirements without using a much greater amount of material – thanks to the GH 4Z weave system:

Example bending radius
GH versus DIN standard (924mm):
- C/42 TITAN X-TREME 420mm
- C42/ TITAN COMBAT 540mm
- C/42 TITAN 3F 620mm
- C/42 TITAN ATTACK 420mm
Example abrasion test*
GH versus DIN standard:
- L3 DIN requirement 600 -> C42/TITAN X-TREME 800
- L2 DIN requirement 400 -> C/42 TITAN COMBAT 600
- L1 DIN requirement 200 -> C/42 TITAN 3F 250
*Abrasion test: The DIN working pressure of 16 bar must be achieved after the given number of revolutions.
What’s inside matters
The rubberized lining was made necessary by the evolutionary transition from natural fibers such as hemp to synthetic fibers, as these don't swell in contact with water. Without the rubber lining, the hose would leak!
Gollmer & Hummel exclusively uses EPDM instead of SBR for the extremely smooth lining, and therefore achieves
During GH flatline vulcanization, the lining is “married” to the inner hose by steam.
The finished product remains very flat and fits effortlessly in any hose basket or GH hose pack carrying system!
Impact and friction protection is required for DIN performance levels 2 and 3. We recommend also using the GH HOSE GUARD for performance level 1, to extend the life of your hoses.
It protects the hose at the end of the binding from defects, such as damage to the lining from external influences.
With the GH EASY-FIX EVO 2 we developed ourselves, fitting and removing pressure couplings is child’s play, even for untrained users: save time and money compared with conventional wire binding.
Conventional DIN pressure couplings (2008 or later) in sizes C/42, C/52 and B/75 can be used.
We designed and developed this assembly device because everyday heroes have more important things to do!
