History
Since 1965, Thermionics Laboratory has manufactured RL vacuum and pressure fittings. The fittings were originally developed in the 1940's by the Lawrence Radiation Laboratory. Initially they were used as connectors between leak detectors, mechanical pumps, and water lines through vacuum systems. However, in recent years, they have been found to be very versatile, with many uses in pressure environments. The fact that they are economical, dependable, and easy to install has been a major reason for their popularity in the vacuum industry.
Materials
RL fittings are available in a choice of brass or stainless steel. (Please specify your choice when ordering.) They are machined from solid bar stock. They may also be specially ordered in Teflon®, nylon or any machinable plastic. Brass fittings have been most popular, and a large inventory is maintained at the factory to ensure prompt shipment. All RL fittings are bakeable to 200°C (392°F). Bakeout is usually required to achieve pressures of 1 x 10-7 Torr.
Assembly of RL fittings is quick and easy. Assembly is accomplished by simply hand-tightening each fitting as it is added to the system. Some fittings may need to be brazed or soldered onto pipes or tubing to fit the demands of your system; however, no special tools are required with normal installation.
RL fittings are supplied in a large selection of sizes. The normal sizes used are: 1/8”, 3/16”, 1/4”, 3/8”, 1/2”, 5/8”, 3/4”, 7/8”, 1”, 1-1/8” special sizes may be requested.
