Types of Fittings

  • 45 Elbow – make 45° changes of direction in the run of pipe.
  • 90 Elbow – make 90° changes of direction in the run of pipe.
  • 180 Return – make 180° changes of direction in the run of pipe.
  • Bend -
  • Cap – seals the end of pipe.
  • 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.
  • Eeldolet – a welding branch for a 90° fitting.
  • 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 Bushing -
  • 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.
  • Socolet – a Socket branch for a pipe.
  • Saddle – a saddle or tapping saddle is used when you do not want to shut down a pipeline, but want to add a branch.
  • Split Tee – wraps around a pipe and has one branch 90° from the main run of pipe, used when you do not want to shut down a pipeline, but want to add a branch.
  • Square Head Plug – seals the threaded end of fitting.
  • Straight Cross – has two branch 90° from the main run of pipe.
  • Straight Tee – has one branch 90° from the main run of pipe.
  • Street Elbow – a 90° elbow with a threaded male one end and threaded female other end.
  • Stub-in – it is the term for a branch of pipe welded directly into the side of a main pipe run. Also a stub-in (long/short) is a fitting with a flared end that a lap joint flange slides over allowing it to rotate in order to align with a mating flange.
  • Swage -
  • Sweepolet – a welding saddle branch for a pipe.
  • Reducer -
  • Reducing Cross – has two smaller branchs 90° from the main run of pipe.
  • Reducing Coupling – joins two different outside diameter pipes togeather.
  • Reducing Tee – has one smaller branch 90° from the main run of pipe.
  • Reinforcing Saddle – these are split in two pieces that fully encircle the branch connection.
  • Round Cap – seals the threaded or plain end of pipe.
  • Round Head Plug – seals the threaded end of fitting.
  • Threadolet – a threaded branch for a pipe.
  • Union – a screwed joint design consisting of three interconnected pieces.
  • Weldolet – a welding branch for a pipe.
