This SAE Recommended Practice presents information which is intended as a guide for proper designing, selection, application, and servicing of liquid, formed-in-place gasket (FIPG) materials.

Definition and Description—Formed-in-place gasket materials are liquids of varying consistencies which can be applied to one of the mating joint surfaces before assembly. When parts are mated, the FIPG material is capable of flowing into voids, gaps, scratch marks, and so forth, and cures to form a durable seal. The concept offers a convenient way of manually or automatically dispensing a seal of varying patterns for assembly. Generally, two types of FIPG materials are used, RTV (Room Temperature Vulcanizing) silicones and anaerobic methacrylate esters. Other types of materials are available but restricted to limited applications and, therefore, are not covered in this manual. The following description and properties for each type of material will help determine the recommended choice of material for a given application. One should thoroughly test any application, and independently conclude satisfactory performance before making final selection.

Rationale—The Powertrain Systems Group has been unable to convene a group of subject matter experts to perform the 5 year content review of this document. Under these circumstances, it is recommended that this Recommended Practice be cancelled.
