Application

Pipelines that expand and contract due to changes in outside temperature or differences in the temperature of transported fluids.
Pipelines where ground subsidence causes misalignment in equipment or tanks.
Pipelines that may shift due to natural disasters such as wind or earthquakes.
Pipelines affected by twisting or rotational forces.
Pipelines in seismic-isolated buildings that must absorb building-to-ground movement (vertical, horizontal, or diagonal).

Item	Specification
Nominal Diameter	20–300
Maximum Operating Pressure	2.0 MPa
Pressure Test	4.0 MPa
Maximum Operating Temperature	220°C

Compliant Product
Complies with SHASE-S 007 (Standard of the Society of Heating, Air-Conditioning and Sanitary Engineers of Japan).
Absorbs Large Expansion in Compact Space
Suitable for long pipelines in large factories or university district heating systems. Fewer joints and supports are needed, reducing installation cost compared to other joints.
Wide Application Range and Long Life
Uses a unique packing material with excellent heat, cold, oil, wear, and corrosion resistance.
Strong Fixation Even with Low Torque
Requires only small torque for rotation during expansion and contraction. Also reduces need for piping guides and restraints, lowering overall cost.
Rust-Proof Processed Ball
The ball undergoes industrial chrome plating to prevent damage to the gasket caused by rust.
Air-Tight Construction with No Leaks
A simple packing and seal structure ensures improved airtightness.
Simultaneous Absorption of All Movements
Absorbs various movements including piping displacement, bending, twisting, and rotation.
Robust Structure
Offers greater durability and water hammer resistance compared to other types of joints.
Predicts Mutual Interference
Can simulate mutual interference at the design stage, ensuring safety verification in advance.

After air or water flow begins, if signs of leakage appear during use, please tighten the hex bolts or hex nuts on the cover evenly by about 6–1 full turns.
Do not insulate area A as shown in the diagram on the right.
Avoid using the product at an inclination exceeding the maximum allowable bending angle (θ° = 8°).
If this angle is exceeded, check and correct the fixings and guides as needed.
