Notes:
Gaskets made from SBR (Styrene Butadiene rubber) with a thickness of 3mm are standard. For information on gaskets made of special types of rubber, for applications involving air or liquid temperatures in excess of 150° F (65° Celsius), or for chemical, hydrocarbon, or other special service applications, and for installations in contaminated soils where permeation through gaskets might be a concern, contact ACIPCO for recommendations. SBR gaskets with cloth inserts are available.

Standard bolts and nuts are manufactured in accordance with ASTM 307, Grade A, carbon steel hot-dipped galvanized. For other bolt and nut material, please contact ACIPCO.
