Fittings

Push-in fittingsFittings can be differentiated according to their functional principle. Push-in fittings are the standard on the market and the most widely used. They are characterised by the easy tube release function, i.e. by actuating a releasing ring. These fittings are used with the standard O.D. tubing that is commonly available on the market.
Barbed fittingsBarbed fittings are, historically speaking, the predecessor of push in fittings. Standard I.D. tubing is inserted via a nipple here. With the CK variant, a union unit provides additional mechanical protection.
Threaded fittingsThreaded fittings are connecting elements that are used to create threads from existing threads. No tubing can be directly connected here.
Click fittingsThe click fitting NPKA is made entirely of polymer and does not contain any metal at all. Furthermore, the patented release mechanism is unique on the market. The fitting NPKA is a good choice when you want to quickly and easily install tubing with one hand.
