New push-to-connect NITRA fittings are designed to work with 1/4-inch and 5/16-inch flexible pneumatic tubing and can be easily added to existing circuits. NITRA pneumatic miniature pressure regulators have an adjustable range of 15 to 120 psi and a built-in relief valve to exhaust over-pressure. Also available are 0 to 170 psi pressure gauges with metal gauge housings. Pressure indicators with either green or orange pressure indicator buttons have an adjustable range of 29 to 145 psi. New 2-way and 3-way inline hand (manual shutoff) valves have a range of 0 to 150 psi and are available with or without locking capability. 7 to 150 psi quick exhaust valves are ideal for use with pneumatic actuators that require a very fast stroke speed. NITRA inline fittings start at $8.75 and are backed by a one-year warranty.
