YDK THREADED RUBBER FLEXIBLE JOINT | MODEL: KJGD(T)-16

During the operation of water supply and drainage, HVAC, and fire protection piping systems, vibration from pumps, thermal expansion and contraction, and misalignment between pipe sections are the leading causes of cracking, bursting, and leaking joints. The cause of these problems usually lies in the rigid pipeline having no point that absorbs vibration, so the forces are transmitted straight into the weakest joint. The YDK threaded rubber flexible joint is the optimal technical solution for handling this situation on small and medium-sized pipelines.

Overview of the YDK threaded rubber flexible joint

The threaded rubber flexible joint (also called a threaded flexible joint or a threaded rubber connector) is a short connector consisting of an elastic rubber body in the middle and a threaded union end at each side. This accessory reduces vibration, reduces noise, and compensates for small misalignments between two pipe sections.

The YDK Model KJGD(T)-16 uses a twin-sphere rubber body, for pipelines from DN15 to DN80.

• Flexible union connection design: A threaded union end at each side of the joint makes it extremely fast to screw into the pipeline, convenient for installation in tight corners, without welding or complicated flange bolting.
• Multi-layer rubber body with outstanding elasticity: The twin-sphere rubber body is reinforced with nylon fiber layers, increasing its ability to flex, absorb mechanical vibration, and withstand high pressure.
• A choice of connection materials: The threaded union end can be supplied in cast/forged carbon steel (Q235) or stainless steel (201, 304, 316, 321) to match each type of fluid environment precisely.

Dimension and displacement table

Notes:

• Extension / Compression: axial displacement
• Lateral deflection: permitted offset between the axes of the two pipe ends
• Angular deflection (a1+a2): permitted total angular misalignment

The threaded rubber flexible joint is suitable for absorbing vibration and compensating for small misalignments. Using the joint to correct a pipeline that was installed out of alignment beyond its limits will cause the rubber body to fatigue quickly and crack early.

Notes when choosing the material of the YDK threaded rubber flexible joint

For the same model, the rubber material of the threaded flexible joint directly affects the service life of the joint.

• EPDM: common for clean water, hot water, and HVAC systems. Not suitable for mineral oil.
• NBR: used for fluids containing oil and for fuels.
• FKM: used for high-temperature environments and chemicals.
• PTFE (lined): used for strongly corrosive chemicals.
• NR, CR, IIR: selected according to the specific operating requirements of the system.

As for the union end connecting the joint:

• Q235 steel suits ordinary water systems in dry environments.
• Stainless steel 304 suits where long-term rust resistance is needed.
• Stainless steel 316 is for environments with chlorides or chemicals.
• Stainless steel 201 and 321 can be chosen according to the specific requirements of each project.
