3000 LB Threaded Couplings ASTM A105 Forged Fittings

3000LB threaded couplings have the most widely using range.ASTM A105 forged fittings is carbon steel fittings belong to American Standard.Threaded couplings have two types:Half and Full.The other pressures could be chosen:#2000,#6000.

Rated 4.7/5 based on 317 customer reviews

3000LB threaded couplings are the most common couplings among all types of couplings,ASTM A105 forged fittings are very popular because carbon steel have great functions with affordable price,and forged fittings have excellent performance in high pressure environments.


Pressures can be chosen of threaded fittings:2000LB,3000LB,6000LB.


Shapes of Couplings:

Straight: It is a kind of pipe coupling with the same diameter at both ends.

Reducing: The two ends of the coupling have different sizes


Types of Couplings:

Full Coupling: Both ends of the full thread coupling are threaded.

Half Coupling: One end of a half thread coupling is threaded and the other end is welded.


Notes:These types and shapes are suitable both THD couplings and SW couplings.
