subsequent assembly. The snug fit and the hard section of the gasket, in conjunction with the design of the buttress, act to restrain the gasket against dislodgment during assembly. Additional internal pressure results in increased tightness of the seal when pipe is either in straight alignment or deflected. Gaskets made of SBR (Styrene Butadiene Rubber) are standard. For information on gas- kets made of special types of rubber, for applications involving air or liquid tempera- tures in excess of 150°F, or for chemical, hydrocarbon or other special service applica- tions, and for installations in contaminated soils where permeation through gaskets might be a concern, consult AMERICAN for recom- mendations. See Table 2-1. Fastite Lubricant AMERICAN Fastite Joint Lubricant is a non -toxic water soluble material imparting nei- ther taste nor odor to the conveyed water and is ANSI/NSF 61 approved. The lubricant is suitable for use in hot or cold weather and will adhere to wet or dry pipe. AMERICAN Fastite Joint Pipe Table No. 2-1 can be assembled when submerged, though for such installation, special AMERICAN underwater joint lubricant is recommended. See Table No. 2-5 for appropriate lubricant quantities. Fastite Joint Materials Standard joint materials include Fastite plain rubber gaskets and a sufficient supply of Fastite joint lubricant. Fastite pipes are most often readily joined with available excavating equipment; however, assembly tools can be supplied by AMERICAN on a loan basis with a nominal deposit which is refundable upon return of tools in good condition. Fittings AMERICAN Fastite or Flex -Ring fittings and AMERICAN Mechanical Joint Fittings are used with Fastite Joint pipe. See Sections 4 and 5. Coating and Lining AMERICAN Fastite Joint Pipe can be fur- nished asphaltic coated, cement lined, or with special coating or lining where required. See Section 11.

Refer to Section 11 for temperature and service capabilities of pipe linings. Refer higher temperatures or other special requirements to AMERICAN for recommendations regarding suitable gasket material. }This gasket rubber is chemically resistant in the non -potable water uses shown but is not as resistant to permeation in potable water applications as FKM. All Fastite gaskets made from the materials in the above table are suitable for use with water containing normal concentrations of chloramine. Where increased resistance to chloramine is desired, neoprene or fluoroelastomer matey als should be considered. 2-7
