MALLEABLE IRON FITTINGS <br />General Assembly of Threaded Fittings <br />1) Inspect both male and female components prior to assembly. <br />• Threads should be free from mechanical damage, dirt, chips and excess cutting oil. <br />• Clean or replace components as necessary. <br />2) Application of thread sealant <br />• Use a thread sealant that is fast drying, sets -up to a semi hard condition and is vibration resistant. Alternately, an anaerobic <br />sealant may be utilized. <br />• Thoroughly mix the thread sealant prior to application. <br />• Apply a thick even coat to the male threads only. Best application is achieved with a brush stiff enough to force sealant down <br />to the root of the threads. <br />3) Joint Makeup <br />• For sizes up to and including 2" pipe, wrench tight makeup is considered three full turns past handtight. Handtight engagement <br />for'/i' through 2" thread varies from 41/2turns to 5 turns. <br />• For 2'/2' through 4" sizes, wrench tight makeup is considered two full turns past handtight. Handtight engagement for 2'/2" <br />through 4" thread varies from 5'/2turns to 6'/4turns. <br />PF-11.13 <br />
