Spherical Rubber Flexible Joint "F-FLEX"

Vibration absorption, absorption of piping expansion and displacement, excellent vibration isolation effect and pressure resistance.

"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.

Spherical Flexible Joint "D-FLEX"

The liquid contact part is made of fluororesin, which has excellent heat resistance and chemical resistance, while also possessing properties such as water repellency, oil repellency, and non-stickiness.

"D-FLEX" is a spherical flexible joint coated with synthetic rubber on the outer surface of fluororesin, handled by Chūnichi Giken Kōgyō Co., Ltd. Since the liquid-contacting part is made of fluororesin, it has excellent heat resistance and chemical resistance, while also possessing properties such as water repellency, oil repellency, and non-stickiness. 【Usage Range】 ■ Maximum operating pressure: 1.0 MPa (However, this may vary depending on usage conditions.) ■ Maximum operating temperature: 100°C (However, this may vary depending on usage conditions.) ■ If the fluid is a gas, the maximum operating pressure may change, so please inquire. (1) It cannot be used in locations such as the delivery side of pressurized or booster water pumps where pressure fluctuations occur frequently. (2) Due to the material properties, there may be a decrease in sealing performance. In this case, please perform additional tightening or use a gasket. *For more details, please refer to the PDF document or feel free to contact us.

Cylindrical Flexible Joint "T-FLEX S"

The liquid contact part is made of fluororesin, which has excellent heat resistance and chemical resistance, while also possessing properties such as water repellency, oil repellency, and non-stickiness.

The "T-FLEX S" is a cylindrical flexible joint coated with synthetic rubber on the outer surface of fluororesin, handled by Chūnichi Giken Kōgyō Co., Ltd. Since the inner surface is straight, there is no liquid pooling. 【Usage Range】 ■ Maximum Operating Pressure: 1.0 MPa (However, this may vary depending on usage conditions.) ■ Maximum Operating Temperature: 100°C (However, this may vary depending on usage conditions.) ■ If the fluid is a gas, the maximum operating pressure will change, so please inquire. *If used beyond the maximum operating pressure (1.0 MPa), we will conduct a separate structural review, so please inquire. (1) It cannot be used in areas such as the delivery side of pressurized water pumps where pressure fluctuations occur frequently. (2) Due to the material properties, there is a possibility of decreased sealing performance. In this case, please perform additional tightening or use a gasket. *For more details, please refer to the PDF document or feel free to contact us.

Expansion Joint "EP Joint" [PL Type Large Diameter]

Pressure type! Absorbs vibrations, noise, expansion, and displacement in piping systems! Active in absorbing expansion and displacement in factory equipment piping and water supply and drainage piping!

Expansion joints (rubber joints) are used to prevent vibrations and noise generated from piping systems, absorb expansion and displacement due to temperature and pressure changes, as well as to accommodate various dimensional fluctuations during construction and mitigate or prevent the effects of earthquakes and ground subsidence. They are considered essential components in piping installations. The E-P joint was launched in 1970 (Showa 45) as a low-pressure R type for elevated water tanks, and since then, it has added new products to meet customer needs, including the integrated high-pressure P type PTFE F type. Today, it is used by a wide range of customers in various industries, from household drinking water to chemical plant piping. 【Features】 1. Has a larger allowable displacement than the P type. 2. Stability in durability due to the combination of strong reinforcing fibers and reinforcing steel wires. 3. Uses EPDM for the inner and outer rubber, offering excellent chemical resistance and weather resistance. 4. Excellent for installation work due to the use of loose flanges. For more details, please contact us or refer to the catalog.

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.
