"F-FLEX" is a flexible joint made of spherical rubber, handled by Chūnichi Giken Kōgyō Co., Ltd. It has excellent vibration absorption, accommodates expansion and displacement of piping, and offers superior vibration isolation and pressure resistance. 【Usage Range】 ■ Maximum operating pressure: 1.0 MPa (however, this may vary depending on usage conditions.) ■ Maximum operating temperature: 70°C (however, this may vary depending on usage conditions.) ■ If the operating pressure is negative (vacuum), please use the embedded rubber type. ■ If the fluid is gas, the maximum operating pressure will change, so please inquire. ■ For fluids such as wastewater and powders that tend to accumulate in the mountain area, the embedded rubber type is recommended. (1) Cannot be used for hot water piping. (Please use D-FLEX.) (2) Cannot be used for pool water. (For circulation pumps around pool water, please use D-FLEX.) (3) Cannot be used in areas where frequent pressure fluctuations occur, such as the delivery side of pressurized or booster water pumps. (4) Generally, cannot be used with fluids or installation locations that may degrade the elasticity of the rubber. *For more details, please refer to the PDF document or feel free to contact us.

Water cooling and liquid cooling joints (couplings, connectors, fittings)

The NS series allows for one-touch connection without any liquid leakage. Significant cost reduction from stainless steel fittings with super engineering plastic fittings!

By using the NS (Non-Spill) series, which prevents water leakage during attachment and detachment, you can avoid the risk of splashing onto electronic devices. Additionally, by using polysulfone coupling (such as HFC35 and HFC57), which is a super engineering plastic, significant cost reductions can be achieved compared to stainless steel couplings. There are also many products that can be used from ultra-low temperatures (minus 40 degrees) and have excellent weather resistance. You can watch a demonstration video at the following link: http://www.youtube.com/watch?v=R55q-mLkXE0 We also sell metal non-spill couplings made from materials such as stainless steel and aluminum. Furthermore, some metal couplings can withstand temperatures up to 204 degrees. Please contact us for more details.
