Quick Connect Couplings and Spray Nozzles
Coupling quickly matters as much on the water side as in compressed air, but under different terms: not valve losses in bar, but corrosion, limescale and varying water quality. This branch holds 43 items. The overview of the water area is under water fittings and irrigation equipment.
Nickel-plated brass throughout
All 43 items are made from nickel-plated MS 58 brass. That is not an economy option but the sensible choice for standing and moving water: the nickel layer prevents tarnishing and makes cleaning easier. Where drinking water is involved, the stricter requirements of claw couplings for drinking water apply.
PN 16 bar across the whole range
Operating pressure is PN 16 bar throughout — well below the PN 35 bar of the air couplings under quick-release couplings with European plug-in profile, but matched to usual line pressure in building and irrigation networks. For higher pressures on site, hose clamps and crimping sleeves and the construction fittings point the right way.
NBR, HNBR or EPDM by medium
The sealing material is differentiated: NBR on 22 items for the normal case, HNBR on eleven for higher temperatures and better ageing resistance, EPDM on six for hot water and cleaning agents. The seal governs service life more than the base material does. For claw technology see claw couplings and spray nozzles.
Free flow or shut-off on both sides
27 items offer free flow, ten shut off on both sides. Free flow means full volume flow with no valve — sensible where a shut-off valve sits ahead of the coupling anyway. Accessories and adapters are under accessories for water couplings, watering wands under watering wands.
Connection sizes from 13 to 25
Connection sizes run from 13 through 16 and 19 to 25, plus G 1/2 female thread. That covers garden and industrial hoses alike. For hygiene requirements see versions for strict hygiene requirements, for the compressed-air side Pneumatics, on the manufacturer Luedecke GmbH.
