Notes:

1. All parts listed are designed for 30" Hg (full vacuum) and have a maximum test at 26" Hg due to facility altitude and equipment limitations.
2. Maximum operating temperature of 250ºF for EPDM, Butyl, Hypalon®, and Viton®; 225ºF for Neoprene; 210ºF for Nitrile; 180ºF for Pure Gum Rubber; 300ºF for EPDM and Butyl in air service at 25 PSI maximum; higher pressure and temperature ratings available.
3. All sizes can be supplied with a filled arch reducing their movements by 50% and increasing the spring rates fourfold.
4. For full product specifications and installation instructions, see SPEC 1015-1 and ININ 1015-1. Gross weights include retaining rings.
5. WARNING: Control units (sold separately) must be used when piping is not properly anchored. Number of rods are dependent upon maximum field test pressures. Expansion joints may operate in pipelines carrying fluids at elevated temperatures and pressures, so precaution should be taken to ensure proper installation and regular inspection. Care is required to protect personnel in the event of leakage or splash. Adequate floor drains are always recommended.
6. Movements are non-concurrent. Contact General Rubber for concurrent movements, and for sizes not shown up to 144" I.D.
7. Retaining rings are typically “L” shaped for sizes 1” through 16”, and can be flat depending on internal reinforcements and for sizes 18” and larger.
8. Standard 125/150 lb. drilling includes, 1"-24" with ANSI B16.1 Class 125 lb./B16.5 Class 150 lb., 30"-60" with ANSI B16.1 Class 125 lb./ B16.47 series A, Class 150 lb., 72"-108" with ANSI B16.1 Class 125 lb./ AWWA C207 Class B.
