FITTINGS AND TUBING
Fittings and tubing for misting systems
Quick-connect fittings and polyamide tubing: the line that holds the system together.
Three consistent families: the 1/4″ line for compact systems, the 3/8″ line for extended runs and higher flow rates, and the stainless steel compression line for demanding or exposed installations.
Each line includes twelve fittings — line start, nozzle holder, union, elbow, tee, cross, line end, plug, adapter, reducer, line-start fitting and shut-off valve — sharing the same assembly logic, so the system can be extended or modified without redesigning it.
- Working pressure100 bar
- Diameters1/4″ · 3/8″ · stainless 10–12 mm
- Maximum line flow6 – 20 l/min
- Maximum line lengthup to 200 m
- Operating temperature−20 / +80 °C
Choosing the line is not an assembly detail: it determines the available flow, the length of the run and the pressure drop down to the last nozzle. The colour of the sections below distinguishes the two quick-connect families — 1/4″ and 3/8″ — from the stainless steel compression line.

Why choose it
Two lines, one logic
1/4″ for compact systems up to 6 l/min, 3/8″ for extended runs up to 11 l/min: the same twelve fittings and the same assembly logic.
Quick-connect
Quick-connect ends remove threads and sealants along the line: assembling, modifying or extending the system takes minutes.
PA 12 tubing
Black polyamide rated to 100 bar in 25, 50 and 100 m coils: flexible in bends, stable over time, suitable for exposed runs.
Stainless compression line
For demanding installations: stainless steel compression fittings on 10 and 12 mm tubing, 85 Nm tightening torque and lines up to 200 m.
Complete range
Line start, nozzle holder, union, elbow, tee, cross, line end, plug, adapter, reducer and shut-off valve: nothing to source elsewhere.
Safety margin
100 bar working pressure against a burst pressure of 200 to 300 bar depending on the line: the system runs with a wide safety factor.
