-
Bend -

Concentric Reducer – centerline of the inlet and outlet is at the same level.
-
Coupling – joins two outside diameter pipes togeather.
-
Dished Head Cap – has a straight tangent with a rounded head.
-
Eccentric Reducer – centerline of the inlet and outlet are at different levels, offset is equals 1/2 times the larger ID minus the smaller ID.
-

-
Flat Bushing -
-
Flat Head Cap – flat plates normally cut for pipe at the site.
-
Full Coupling – also called coupling, joins pipe two pipe or nipples.
-
Half Coupling – can be welded directly to the run pipe to make a branch connection.
-

-
Hex Head Plug – seals the threaded end of fitting.
-
Lateral – a welsed branch 45° from the main run of pipe.
-
Mitered Elbow – a elbow is fabricated from pipe and is not a fitting.
-
Nipolet – a one piece fitting threaded branch with a nipple for drains, valves and vents.
