Rubber Joint "SB Joint"

Rubber Joint "SB Joint"

Adopting a spherical shape for the main body! A rubber joint that withstands high operating pressure and negative pressure of -0.1 MPa.

The "SB Joint" is a rubber joint that can significantly prevent vibration noise from air conditioning equipment and other sources. The main body, composed of special heat-resistant rubber and reinforced cords, experiences minimal dimensional changes and degradation due to high temperatures, allowing for relatively long-term use. Additionally, since synthetic rubber is used in the main body, it easily deforms under external forces, reducing the hassle of piping. 【Features】 ■ Excellent pressure resistance ■ Structure with minimal dimensional changes ■ Easy alignment for piping ■ Outstanding heat resistance and durability ■ Significant absorption of vibrations and noise, etc. *For more details, please download the PDF or feel free to contact us.

Expansion "E Series A Type"

Expansion "E Series A Type"

Expansion that achieves a large displacement due to the arch structure!

The "E Series A Type" is a multipurpose rubber joint that absorbs expansion, contraction, and eccentricity due to temperature changes in the piping, thanks to its arch structure. Because the axial reaction force is small, installation onto the piping is particularly easy. Additionally, the arch structure allows for large displacement. [Types] ■ EA1: Single arch type (for internal pressure and vacuum) ■ EA2: Double arch type (for internal pressure and vacuum) *For more details, please download the PDF or contact us.

Estimated useful life: rubber joint

Estimated useful life: rubber joint

Calculate the estimated useful life based on usage conditions! Please use it as a guideline for regular inspections and replacement timing.

The "rubber joint" is made of organic materials such as rubber and synthetic fibers, so it has a limited lifespan. Additionally, its lifespan can vary significantly depending on the usage conditions. By downloading the PDF document, you can view the "Service Life Coefficient Table" and the "Pressure Unit Conversion Table." Please use these to estimate the expected service life based on your usage conditions, as a guideline for regular inspections and replacement timing. The standard service life is set assuming the fluid is water. *For more details, please refer to the PDF document or feel free to contact us.*
