<Remarks/Precautions>
- If the fluid is liquid and the joint is used in an overhead pipe, the weight of the internal fluid may cause the joint to sag.
- The inner surface is also uneven, and solids may accumulate, so please be careful when using slurry fluid.
- Due to the thin body thickness, it cannot be used for abrasive fluids.
- Due to the high flexibility of the main body, it may protrude sideways when pressurized.
- Please contact us for non-standard specifications (diameter, length, etc.).
- Due to the manufacturing method, the plating on the flange may be discolored or mottled, but this does not affect performance.
