Pipe Size
Butt Nipples are intended for joining
couplings or female threaded components
end to end without exposing male threads.
Butt Nipples have standard NPT male
threads on both ends. Threads may have
fewer imperfect threads due to reduced
nipple length. Butt Nipples are fabricated
from ASTM A53 Schedule 40 welded pipe.

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.
