Discover air & material fittings, quick & safety couplings, plug nipples (nominal widths), hose barbs, reducers as well as gauge/regulator ports. From nominal widths & plug profiles to thread standards (BSPP/BSPT/NPT/metric) and sealing principles through to flow sizing – we configure the connection precisely for your gun and supply.
Tight, safe connections with minimal pressure loss, quick changeover thanks to quick/safety couplings and standardized plug profiles, plus a stable media supply for reproducible finishes – from workshop to production line.
Nominal width & plug profile determine flow; thread standards and sealing concepts (tapered vs. parallel with sealing washer/O-ring) ensure tightness. Safety couplings vent before disconnection and reduce whipping hazards. Check material fittings for media compatibility; observe pressure ranges per manufacturer approvals.
Quick/safety couplings, plug nipples, hose barbs, reducers, gauge/regulator ports, sealing washers/O-rings as well as cleaning & test media. We handle the compatibility check (standard, nominal width, sealing) and integration in workshop and on the line.

Fittings connect guns to the air and material supply: quick/safety couplings, plug nipples, hose barbs, reducers and gauge ports. They ensure tight, safe and high-flow connections.
Relevant are nominal width/plug profile, thread standard/size (BSPP/G, BSPT, NPT, metric), sealing principle (tapered vs. parallel with sealing washer), required flow and pressure range. For pressure relief and safety, a safety coupling is recommended.
Thread tolerance and sealing surface quality, correct sealant (PTFE only for permitted tapered threads), nominal width/cross-section, valve geometry of the coupling, and media compatibility. These determine tightness, pressure drop, noise and occupational safety.
We supply fittings for SATA, DeVilbiss, Anest Iwata, Graco, Wagner, Walther Pilot, Binks, Sames, Ecco Finishing, WIWA, Krautzberger and Sagola – including consulting on nominal widths, thread standards, sealing concepts and process integration.
We support thread/system identification, sealing & flow tuning and compatibility checks with your gun – for safe, reproducible connections.
