CAST IRON THREADED FITTINGS
Anvil standard and extra heavy cast iron threaded fittings
are manufactured in accordance with ASME B16.4. Plugs and
bushings are manufactured in accordance with ASME B16.14.
NOTE: Figure 367 Concentric Reducers do not meet the overall length
requirement of ASME B16.4. All other dimensions are in compliance.
For Listings/Approval Details and Limitations, visit our website at
www.anvilintl.com or contact an Anvil Sales Representative.

CAST IRON THREADED 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.
