AutomationDirect Adds Pneumatic Tubing and Fittings

AutomationDirect now offers NITRA™ pneumatic tubing and fittings for use in compressed air applications.

NITRA tubing is available in polyurethane and nylon styles, in inch and metric sizes from 5/32 inch or4mm up to1/2 inch or 12mm; tubing is available in 100 and 500-foot packages. Polyurethane tubing is available in black, blue and clear, and has a hardness specification of Shore A 98. The tubing offers superior kink resistance and is strong and flexible. Its tight outside diameter tolerance makes is ideal for use with NITRA push-to-connect fittings.

NITRA Pneumatic Tubing and FittingsNITRA Nylon 12 tubing carries a hardness specification of Shore D 70. Nylon tubing is designed for applications requiring higher working pressures and better heat/chemical resistance. Available in black, blue and natural, this strong, yet lightweight tubing has a low moisture absorption rate so it will remain flexible with a longer life than other nylon tubing.

A variety of NITRA push-to-connect fittings are also available, including straight, elbow, tee and wye styles. Fitting bodies are made of a strong thermoplastic with stainless steel gripping claws, and are designed to withstand working pressures of -29.5” Hg to 150 psi and a working temperature range of 32° to 140°F. Threaded components are made of nickel-plated brass and have pre-applied Teflon thread sealant. The bodies of threaded elbow and tee fittings can be rotated after installation, allowing for variations in piping direction.

NITRA pneumatic push-to-connect flow control valves are designed to provide accurate airflow regulation for precise motion control of pneumatic cylinders. The flow control bodies are made of strong thermoplastic and have stainless steel tube gripping claws and are available in meter-in, meter-out, and in-line configurations.
