Festo Pneumatic Fitting Reducer Nipple, , Nickel Plated Brass, POM, Stainless Steel, Push-in 4 mm to 3 mm, 14 Bar QSM-4H-3

Festo QSM-4H-3 is a pneumatic reducer nipple designed to provide compact push-in connections between 4 mm and 3 mm lines within automation and industrial systems. Manufactured using high-grade nickel plated brass, polyoxymethylene (POM), polybutylene terephthalate (PBT), high-alloy stainless steel, and nitrile rubber (NBR), this fitting delivers both chemical resistance and food-grade compliance for use in demanding environments.

Its robust construction supports a maximum operating pressure of 14 bar, allowing it to perform reliably in high-pressure pneumatic control lines and compressed air distribution networks. Operating temperatures range from -10°C to 80°C, ensuring compatibility across varied climates and applications. The push-in end connections facilitate rapid installation and maintenance in factory automation settings.

Constructed from nickel plated brass, POM, polybutylene terephthalate, stainless steel, and NBR. Pneumatic fitting operates as a reducer nipple for connecting 4 mm to 3 mm push-in hoses. 14 bar maximum operating pressure withstands industrial pneumatic demands.

Broad temperature range, from -10°C up to 80°C, supports operation in harsh conditions. Food-grade, chemical-resistant materials maintain durability and compliance for critical applications. Certified to DIN 5510-2, FDA, DIN 73378, Germanischer Lloyd, RoHS, UL standards for transport and safety-critical installations.

Used in pneumatic control lines, food processing plants, electronics manufacturing, and actuator supply circuits. Nickel-plated brass push-in connection offers secure, corrosion-resistant joining.

The QSM-4H-3 is suitable for installations where exposure to chemicals and oils is common. Its NBR seals retain elasticity while resisting pneumatic lubricants, ensuring a reliable seal throughout its working temperature range. Designed for factory automation, food processing, and electronics assembly sectors, this fitting is a trusted choice for high hygiene and mechanical reliability.

Applications include factory automation pneumatic control lines, compressed air distribution in food processing plants, electronics requiring corrosion resistance, and actuator supply lines. The versatile materials and secure design make it suitable for installations requiring compliance with international safety standards.
