NORFLEX® PVC 400 SPECIAL WALL
Highly flexible PVC hose with increased wall thickness ("special wall") for better pressure and crush resistance. Chemical-resistant and crush-resistant. Designed for compressed air supply, coolant transport and as connection hose in machinery and equipment. The extra wall thickness significantly extends the hose's lifetime under continuous pressure.
- Special wall (extra thick)
- Crush-resistant
- −15 to +60 °C
- Highly flexible
- Chemical-resistant
- Cut to length
Why this hose?
NORFLEX® PVC 400 SPECIAL WALL is a variant with increased wall thickness for better pressure and crush resistance than standard NORFLEX PVC 400. The extra wall means the hose tolerates higher pressure without deforming, and the hose can be compressed externally without collapsing.
In practical use this means longer lifetime on compressed air applications and better handling on machinery installations where the hose can be compressed or loaded externally.
Where it is used
In the workshop it sits as connection hose to compressed air tools.
In machinery it's used as coolant transport between process stations.
In everyday talk we call it a "PVC 400 special" — the crush-resistant variant.

Help with material selection
Although this hose isn't ATEX-relevant, these two articles provide useful background on electrical resistance and industrial safety — important if you later combine the hose with electrical equipment or work in mixed environments:

The difference between antistatic and conductive, which resistance limits apply where, and how to measure them correctly.
Industries that use it
NORFLEX® PVC 400 SPECIAL WALL is used where crush resistance is needed:
In machinery and workshop it's standard choice for compressed air installations exposed to external load.
In cooling systems the extra wall thickness gives longer lifetime against crush deformation.
Custom lengths and assemblies
The hose is delivered on rolls and cut to length with couplings as a finished assembly.
For serial deliveries we can establish consistent assembly.
Frequently asked questions
What does "special wall" mean?
The hose has increased wall thickness compared to standard NORFLEX PVC 400. This provides better pressure and crush resistance at the cost of slightly more stiffness.
Does it tolerate compressed air?
Yes. The extra wall thickness is specifically designed for continuous operation under compressed air pressure.
Can I use it for coolant?
Yes, PVC is compatible with most industrial coolants at operating temperatures.
Is it food-grade?
No, this variant is not food-grade. For food choose POLYFLEX or a silicone-based hose.
Is it ATEX-approved?
No, the PVC wall is insulating.
Can I get it with quick-connects?
Yes. For compressed air tools quick-connects are practical — we fit them as a finished assembly.
