MALLEABLE IRON FITTINGS
General Assembly of Threaded Fittings
1) Inspect both male and female components prior to assembly.
• Threads should be free from mechanical damage, dirt, chips and excess cutting oil.
• Clean or replace components as necessary.
2) Application of thread sealant
• Use a thread sealant that is fast drying, sets-up to a semi hard condition and is vibration resistant. Alternately, an anaerobic
sealant may be utilized.
• Thoroughly mix the thread sealant prior to application.
• Apply a thick even coat to the male threads only. Best application is achieved with a brush stiff enough to force sealant down
to the root of the threads.
3) Joint Makeup
• For sizes up to and including 2" pipe, wrench tight makeup is considered three full turns past handtight. Handtight engagement
for 1⁄2" through 2" thread varies from 41⁄2 turns to 5 turns.
• For 21⁄2" through 4" sizes, wrench tight makeup is considered two full turns past handtight. Handtight engagement for 21⁄2"
through 4" thread varies from 51⁄2 turns to 63⁄4 turns.
