Quick Connect Couplings are a fast and easy means of joining various pneumatic and fluid transfer lines. An automatic shut-off valve in the coupler end allows the quick connects to be disengaged without needing a separate ball or line valve. The size of the inlet thread is a good indication on the proper coupler size to use in order to maximize feasibility and flow. A short (3-10 ft) lead-in or whip hose coupled with solid male NPT ends will prolong coupler life as it will absorb vibration and reduce metal fatigue. You can differentiate between various Interchange Series by observing the differences in the nipple/plug nose as well as with differences in the coupler sleeve. These quick connects will interchange with many popular brand names, such as: Amflo, Aro, Camel, Cejn, Coilhose, Dill, Dixon, Foster, Hansen, Lincoln, Milton, Nycoil, Parker, Perfecting, Schrader, Tomco, and Truflate (crossover tables are available).
The basic function of pneumatic hose is to convey pressurized air to actuators, valves, tools and other devices. But there are countless types and sizes of tubing and hose on the market, so engineers should consider a number of important factors to select the right one for a given task.
Pu pneumatic hose processed by Polyurethane, with very good elasticity, PU tube is applicable to occasions of big bending, temperature-resistance, anti-tubing, anti-vibration and twist-resistance, PU hose suitable for various of fittings, easy for piping-work and flexible in application.
Application of PU pneumatic hose :
Used for air brake, automated machinery, coating machinery, all kinds of pneumatic tools, pneumatic & hydraulic machinery, construction, and various pneumatic tools. Polyether-based PA hose is hydrolysis-resistant, anti-bacterial & anti-fungous, and it can be used for gardening, cleaning, water hoses, and other purposes.
Characteristic of pneumatic hose:
Temperature: -40℃(-104℉)to + 90°C (+ 140°F)
These “one-touch” Tube Fittings are designed for air/pneumatic systems up to a maximum of 150 psi and 29.5 in/Hg vacuum. This series is NOT for use with any other types of gas or liquids, and NOT for use in DOT air brakes or in air breathing apparatus. They are suitable for use with polyurethane, nylon, and polyethylene tubing. They have nickel-plated brass and lightweight composite bodies and can be installed/removed easily (remove tubing by pressing the sleeve). The male threaded ends “swivel/rotate” for ease of installation in confined spaces. Also available in stainless steel upon request. Temperature range: +32°F (0°C) to +140°F (60°C).
