Pneumatic fittings connect tubing to threaded ports, manifolds and other components — they're the joints that make a pneumatic circuit. Norgren offers five product families: push-in fittings (Pneufit M/C/D/E/S/10, multi-connectors and Fleetfit) for tool-less assembly with releasable stainless-steel grab-rings, push-on fittings (24 series barb design) for tight bend radii, compression fittings (34/36/43 series) for the most demanding pressure and temperature conditions, threaded connectors (15/16 series with ISO G/R/NPT, plus 0401 rotating joints) for hose and pipe transitions, and quick-release couplings (238 series) for tool-changeover and ad-hoc connections.
Miniature push-in fitting, Ø 3, 4 and 6 mm O/D tube. Nickel-plated brass with releasable stainless-steel grab-ring. Pre-applied thread sealant on taper threads. Ultra-compact — for installations where space is at a premium.
Standard push-in fitting, tube Ø 4, 6, 8, 10, 12, 16 mm O/D; threads M5, M6, 1/8, 1/4, 3/8, 1/2 in ISO G, ISO R and ISO Rc. Impact-resistant PBT body, nickel-plated brass threaded bodies, releasable stainless-steel grab-ring grips PA 11/12 or PUR tube (85, 95 or 98 durometer). Pre-applied thread sealant on taper threads, recessed captive O-ring on parallel threads. Max 10 bar; ambient/media -20…+60 °C; silicone-free NBR seals. Safety warning: must not be used in vehicle air-braking or ancillary systems — use the Fleetfit range instead.
Acetal (POM) push-in fitting, tube Ø 4, 6, 8, 10, 12 mm O/D, with POM and SUS stainless-steel collet. Threads ISO G, ISO R and UNF in 1/8", 1/4", 3/8", 1/2".

Rated to Clean / Dry Room Class 4 to ISO 14644-1 at -40 °C dew point (<0.5 % RH) — making it suitable for cleanroom-grade battery-assembly environments.
AISI 316L stainless-steel push-in fitting for corrosive fluids, aggressive environments and direct food contact. Tube Ø 4, 6, 8, 10, 12 mm O/D; ISO R, ISO G and metric M5 threads. FKM (FPM) 'O'-ring and BSPP thread seal, all raw materials and manufacturing processes silicon-free. Operating pressure vacuum…20 bar, ambient/media -15…+190 °C. Compatible tubing: PA6, PA11, PA12, PE, PUR, PTFE, FEP. NSF 169 certified, conforming to NSF 61 and NSF 372; compliant with EC 1935/2004 Food Contact Materials. Cleanline design with swivel function on all elbows and tees — safe in salty / wash-down environments.
Push-in fitting, tube Ø 4, 5, 6, 8, 10, 12, 14, 16 mm O/D — including the distinctive 14 mm tube size — with extensive thread options (ISO G, ISO R, ISO Rc, NPT). Operating pressure vacuum…18 bar (261 psi); ambient/media -20…+80 °C. Conforms to BS ISO 14743. All BSP taper threads pre-coated with non-PTFE based sealant. Straight adaptors feature internal hexagon for Allen-key tightening. VMQ-free NBR O-rings, silicone-free.

Push-in (Pneufit) for fast, tool-less assembly of pneumatic circuits with PA/PUR tube — the standard modern choice for new installations. Compression (34/36/43) for demanding pressure/temperature, metallic tubing or hydraulic-style duty. Threaded (15/16) for hose-to-pipe or pipe-to-pipe adapters, manifolds and pipework transitions. The 24 series push-on is a niche choice for tight bend radii where push-in won't fit.
Pneufit C, M, 10 and multi-connectors work with PA (polyamide) and PUR (polyurethane) tube, 85, 95 or 98 durometer. Pneufit D works with PA/PUR for food contact (EC 1935/2004). Pneufit S (stainless) handles aggressive fluids in PA/PUR or with metal tubing. Don't use PE tubing in push-in fittings — it can creep and lose seal under pressure.
Pneufit D (acetal/POM) and Pneufit S (stainless steel) are explicitly compliant with EC 1935/2004 Food Contact Materials Regulation, with food-grade EPDM or stainless internals. The Pneufit D is the standard choice for potable water, beverages and drinks dispense; Pneufit S adds aggressive-fluid and wash-down resistance.
Press the colored release ring toward the fitting body (not away from it) and pull the tube straight out. The grab-ring releases as the ring is depressed. Don't twist or angle — straight push, then straight pull. The same fitting can be re-used many times provided the tube end is clean and undamaged (cut a fresh end with a tube cutter if needed).
Pneufit push-in fittings are designed for plastic tube only (PA, PUR; Pneufit® S additionally lists PE, PTFE, FEP). For metal (copper, aluminium, stainless) or hydraulic-grade duty, use the 34/36/43 compression series or matching threaded connectors. Pneufit® S stainless body is corrosion-resistant but the grab-ring still requires plastic tube to grip correctly.
Pneufit® C (standard, PBT + nickel-plated brass, 10 bar, -20…+60 °C, Ø 4–16 mm) — the universal industrial choice. Pneufit® M (miniature, Ø 3, 4, 6 mm) — ultra-compact for tight spaces. Pneufit® D (acetal/POM, vacuum…16 bar, 0…+60 °C) — NSF 51/61, EC 1935/2004, MOCA, ICIM for food and potable water. Pneufit® E (zinc- and copper-free, PA66 + SUS303 stainless, 20 bar, -20…+80 °C, Class 4 cleanroom) — EV battery plants. Pneufit® S (AISI 316L stainless, 20 bar, -15…+190 °C, NSF 169/61/372, FKM seals) — corrosive, wash-down, high-temperature, food-contact. Pneufit® 10 (vacuum…18 bar, -20…+80 °C, Ø 4–16 mm including 14 mm) — extensive thread choice (ISO G, ISO R, ISO Rc, NPT), non-PTFE pre-applied thread sealant.
The 43 series external-nut compression fitting reaches 100 bar (1450 psi) for Ø 4–14 mm tubes and 40 bar (580 psi) for Ø 16–22 mm tubes. Medium covers compressed air, oil, water and low-pressure hydraulic applications. The actual maximum working pressure is limited by the tube being used (e.g. copper tubing with 1 mm wall thickness at +20 °C, or metal/PA tubing per the appropriate spec). For full hydraulic-grade duty, always confirm with the tube supplier and our technical team.
The Pneufit® E body case is moulded in PA66 polyamide with SUS303 stainless-steel body threads — and the whole assembly is rated to Clean / Dry Room Class 4 to ISO 14644-1, at -40 °C dew point (<0.5 % RH). Combined with the zinc- and copper-free construction, this makes it suitable for electric-vehicle battery plants where airborne particulate and metal-ion contamination must be controlled.
Pneufit® C must not be used in vehicle air-braking or ancillary systems — that is the explicit safety warning on its datasheet. The Fleetfit 97400 series is the dedicated commercial-vehicle range: -40…+100 °C, 0–10 bar, brass body (BS 2874 CZ 121/CZ 122) with internal tube support, tubing per DIN 74324, and it is certified to DOT FMVSS 106 (US federal vehicle safety standard for inch fittings), SAE J1131 (inch tubes & fittings), DIN 74324 (metric tubes & fittings) and German TÜV. Use Fleetfit for vehicle pneumatic systems; Pneufit® C for industrial machines.
The 0401 range comes in two speed classes: slow-rotating models (max 50 rpm) for ports 1/8", 1/4" and 3/8", suitable for compressed air or oil (not water); and fast-rotating models (max 2000 rpm) for 1/4" port only, compressed-air only — except for the dedicated vacuum variant (04016200), identified by 'v' marked on the body. The pressure range is 0–7 bar in all cases; the joint must not be subjected to side or end loads.
