Hose & Tube Connectors

Hose and Tube Connectors for Pneumatic and Hydraulic Systems

Hose and tube connectors provide the critical interface between flexible hose or tube and the ports, manifolds, cylinders, valves, and other components in pneumatic and hydraulic systems. The wide variety of connector types, thread forms, and tube or hose sizes used across different equipment makes it essential to correctly identify both the port thread standard and the tube or hose outer diameter before selecting replacement or new connectors. AIMS stocks a comprehensive range of hose and tube connectors in the most common styles and sizes used in Australian industrial and commercial applications.

Push-In Pneumatic Connectors

Push-in (also called push-to-connect or instant fitting) connectors are the standard connection method in modern pneumatic systems using nylon, polyurethane, or polyethylene tubing. They allow fast, tool-free tube insertion and release, which simplifies pneumatic circuit assembly and maintenance significantly. Push-in fittings are available in straight, elbow, tee, cross, and union configurations to handle all standard circuit routing requirements. Brass push-in fittings are the most common, with stainless steel and nickel-plated variants available for food-grade or corrosive environments. Always verify that the tube outer diameter and the fitting size are matched — push-in fittings are sized by the tube OD they accept.

Hose Tail (Barb) Connectors

Hose tail connectors with barbed shanks are used with flexible rubber and PVC hose that is secured with hose clamps. The barbs grip the inside bore of the hose and resist pull-out when the hose clamp is tightened correctly. Hose tail connectors are specified for water, air, chemical, and low-pressure fluid transfer applications. They are available with BSP male or female thread ends, camlock ends, or plain barb-only designs for hose-to-hose connections. Brass construction is standard for general use, while stainless steel and polypropylene are available for chemical and food-grade service.

Compression Fittings for Tube

Compression fittings for metal tube — typically DIN 2353 metric or SAE compression standards — create a reliable, pressure-rated connection for copper, steel, and stainless steel tube in hydraulic and instrumentation systems. The cone and ring compression mechanism deforms to grip the tube and create a metal-to-metal seal without thread sealant. These fittings are reusable with care and provide reliable sealing across a wide pressure range, making them widely used in hydraulic control circuits, instrumentation tubing, and high-pressure pneumatic systems.
