These male elbow connectors are designed to provide reliable 90° connections between threaded ports and tubes of various outer diameters. Available in M5 threads for 4 mm tubes and a range of BSP thread sizes—including 1/8", 1/4", 3/8", and 1/2"—these connectors accommodate tube sizes from 4 mm up to 12 mm O.D. Ideal for pneumatic and fluid systems, they ensure leak-free, durable connections while allowing efficient changes in flow direction within compact spaces. Advantages The Tube Fitting comes in a wide variety of models to meet all your needs in pneumatic piping.Water is admitted conditionally. High performance / high quality The lock-claws grips circumference of the tube evenly.Feeling as good as new, even after many years.PISCO's uniquely shaped elastic sleeve shuts out air leaks. Industry leading wide variety of models. Various sizes of unequal union type makes it possible to handle with just one fitting, although two or more fittings are used before.It reduces the amount of fitting used and enables cost and space saving. Even after installation, the direction of the tubing can be changed freely. Centralized piping is possible. Triple type (PKD, PKG, PKJ) and Twin Triple type (PKVD, PKVG) realize compact centralized piping. Clean-room Package, best suitable for piping in cleanroom, is available. (Optional) Fluorine grease is applied and washed by clean air, then packed in ISO class 6 cleanroom. Clean wash specification, best suitable for various production processes where foreign particles and oil are not welcome, is prepared. (Option for Clean-room Package specification) Deaeration package after vacuum ultrasonic cleaning by HFE (hydrofluoroether) is carried out in the cleanroom. Specifications Standard Fluid medium Air, Water (Conditional*) Max. operating pressure 1.0MPa Max. vacuum -100kPa Operating temp. range 0～60℃（No freezing） Warnings * Make sure to follow the instructions below when the fluid medium is water. Surge pressure must be controlled lower than max. operating pressure when using water as a fluid medium. Tap water in Japan free from foreign substances or contamination can be used. Carry out the evaluation under an actual operating condition for using other kind of water. Be sure to place Insert Ring (WR) into the tube edge when using water as a fluid medium.
