Shop our varied selection of push-lock pneumatic fittings by Airtac. We offer both threaded and union fittings. Each type has the option for either a black or grey release button as well as multiple port sizes from which to choose. These models can be widely used in every kind of pneumatic system. The tubing connection is durable, while the threaded portion is covered with sealant and the M5 thread is attached with a sealing gasket to prevent air leaking over the connection. Our fittings' nickel plated body is anti-corrosion and environmentally friendly, which allows for a broader application.
