Features
Standard Compliant — Conforms to SHASE-S 003 (Standards of the Society of Heating, Air-Conditioning and Sanitary Engineers of Japan).
Leak-Free Airtight Design — Can be used for a long time without replacing the packing.
Long Life — No need to stock spare parts.
Absorbs Large Expansion and Contraction — With a large absorption range, fewer pipe joints and fixed points are required, making it economical. Also absorbs twisting.

Note: The set face-to-face length is the value obtained by subtracting the elongation δe from the maximum face-to-face length. Unless otherwise specified, we will deliver using this dimension.
Precautions for Use
Avoid using the expansion joint beyond the maximum or minimum face-to-face length. If the specified face-to-face length is exceeded, inspect and correct the fixation, guides, and other related components.
