Push-in connectors, manifold and special connectors are used for water, beer and wine installation. In the water treatment market, our products are used in both reverse osmosis machines and water coolers. Our primary objective is customer satisfaction; for this reason we have come up with the most functional and practical solutions in the manifold field, for an intelligent and profitable use. Our 4 and 5-way manifolds are designed to integrate all the necessary functions for both domestic use and non, into a single push-in connector, in order to reduce the numerous combinations present in the fluid circuit.

High and low pressure quick couplers R134 e R1234. The quick couplers for recharging the car air conditioners with R134A and R1234 freon gas are designed to exceed 5000 complete loading/unloading cycles.

Our compressed air couplers are developed according to the Pres Block profile and designed for industrial lines. Available in different internal passage sizes and connections, our couplers are always available in stock. The same joints are also available for oxygen/acetylene used in welding.

Quick couplings, check and ball valves, push-over fittings, bayonet head push-in connectors and custom products. The wide range of plastic quick couplings for vacuum cleaners and whirlpool baths allows the customer to be able to recreate the complete hydraulic layout where a fluid connection is required with a permanent seal guarantee. Our special fittings, available in the catalog for the various applications, allow the completion of the range. The company is always available to study new applications with the customer. In the whirlpool sector our vast range of swivel fittings that the company has been producing for over 20 years gives the customer the possibility to recreate any type of hydraulic circuit.
