Hoses for Spray Guns
Discover air hoses, material hoses, twin hoses as well as antistatic/conductive and heated hoses for workshop and production. From inner diameter (ID), length and bend radius to pressure/temperature ranges and media compatibility through to fitting standards – we design your hose bundle for flow and process stability.
Use & benefits
Constant flow with minimal pressure drop, safe media handling without interactions, and electrostatically conductive design for water-based/conductive materials. Optimized hose packages reduce pulsation, improve the spray pattern and increase process reliability.
Technology & settings
ID & length: choose ID by flow rate, keep lengths short, avoid tight radii. Material: PU/PA for air and flexibility, PTFE or paint-safe rubber compounds for solvent/waterborne coatings. Plan for antistatic/conductive (ATEX) where required. Choose fittings (BSP/NPT/metric) and couplings with sufficient cross-section to avoid bottlenecks.
Accessories & integration
Hose bundles (air/material), quick couplings, reducers/thread adapters, hose protection (spirals/jackets), heating modules, grounding kits, regulators/gauges as well as cleaning & test media. We handle the compatibility check (media, fittings, pressure) and integration in workshop and line.
Key advantages at a glance
- Suitable inner diameter & length for minimal pressure drop

What hose types exist and what are they used for?
There are air hoses for compressed air supply, material hoses for paints/coatings, twin hoses for air + material, antistatic/conductive hoses for safe grounding, and heated hoses for viscous media and consistent viscosity.
How do I choose inner diameter, length and material correctly?
The inner diameter is based on flow rate and permissible pressure drop; keep length as short as possible and as long as necessary. Choose hose material according to medium, temperature and flexibility (e.g., PU, PA, rubber, PTFE). For water-based/conductive media, specify antistatic/conductive.
Which factors influence pressure drop and transfer behavior?
Length, inner diameter, surface roughness, number of couplings/transitions and the medium’s viscosity determine pressure drop. With air, additional losses occur due to tight bends; with material, pulsation and temperature affect delivery stability.
