Parker Hannifin is a leading manufacturer of high-quality brass fittings & valves, tube fittings, quick-connect couplings, rubber & thermoplastic hoses & fittings, and various assembly tools for pneumatic & hydraulic applications in the electronics, aviation & aerospace industries. The extensive Parker product catalogue includes air brake tubings, air hoses & regulators, ball valves, brass pipes, breathers, filter bags, hydraulic accumulator & valves, in addition to the aforementioned products. Parker's low-pressure ball valves are designed to regulate & maintain high-pressure and -volume flow of air, water & oil. These ball valves include SAE & NPT ports, can withstand pressure ranging between 250 to 2000 psi, are available in pipe sizes ranging from 1/4 to 1 inch and feature lever / locking lever handles. Parker's tube fittings & pipe connectors are designed for quick & easy installation of compressed vacuum, air & inert gas piping systems. These 90-degree elbow connectors connect via push-to-connect technology (for 16 to 40 mm connectors), snap ring technology (for 50 & 63 mm connectors) to prevent the forward sliding of the connector half from leading to an insertion depth error and clamshell technology (for 76 to 168 mm connectors) to grip onto the pipe lungs. They have a maximum working pressure of 188 psi when the system is operated between -4 to 140 degrees F and 232 psi when the system is operated between -4 to 115 degrees F. A wide range of pipe connectors, cooling sight glasses, duct & cloth tapes and garden hose connectors & adaptors is available on Raptor Supplies, an authorised Parker Hannifin distributor.
