Pipe Fittings
BMP_Backnut "Backnut" Backnut — A Hexagonal/Octagonal locking back nut used in forming a watertight pipe joint.
BMP_BendWithHeel "Bend With Heel" Bend With Heel — The elbow to connect two pipes at a 90° angle and a low heel inlet suitable for waste water systems.
BMP_Cap "Default Cap" Cap — Piping fitting that covers the end of a pipe. Contains a round hand grip at the open end of the cap.
BMP_Cross Cross Cross — Standard cross is a 4-way piping fittings, where a branch line passes through a tee. It has one inlet and three outlets, or vice versa.
BMP_Elbow "Default Elbow" Elbow — Elbow fittings used to reduce flow resistance and solids deposition when the direction of flow is changed.
BMP_ElbowUnion" Default Elbow" Elbow Union — Standard elbow fitting with hex union at one end. Ideal for joining two pipes at angles, usually 90°, changing direction of flow of liquid
BMP_FlatCap "Flat Cap" Flat Cap — Piping fitting that covers the end of a pipe. Contains a flat hand grip at the open end of the cap.
BMP_H-BranchWye H-BranchWye H-Branch Wye — A branch line is angled to tee in H shape to reduce friction and turbulence that could hamper the flow.
BMP_LateralWye LateralWye Lateral Wye — Wye fitting joins one pipe run to branch that runs in one direction at an angle, usually 45° to the main run. The lateral outlet providing smooth pipe branch.
BMP_ReturnBend ReturnBend Return Bend — "U" shaped bend fitting usually a long radius type making 180° change in direction
BMP_RoundCoupling "Default Transition" Coupling — Plumbing coupling basically connects two pipes of different material and by controlling the main and run diameters to connect the pipes can connect two pipes of different size.
BMP_Stub "Default" Stub — Stub outs used to extend pipe installed below slabs or inside walls out of the structure and into the room and can connect the rest of your plumbing to the pipe later.
BMP_Tee "Default Tee" Tee — T-shaped pipe fitting having two outlets, at 90° to the connection to the main line. A tee is used for connecting pipes of different diameters or for changing the direction of pipe runs.
BMP_Transition "Default Transition" Reducer — A reducer allows for a change in pipe size to meet the flow requirements of the system, or to adapt to existing piping of a different size.
BMP_TwinElbow "TwinElbow" Twin Elbow — Elbow with two ends for diverting flow of liquid in a required angles or branches bent in desired radius.
BMP_Wye "Default Wye" Wye — A standard wye is a "Y" shaped fitting with three openings. A wye is used to create branch lines. It is a type of waste fitting tee which has the side inlet pipe entering at a 45° angle, or an angle other than 90°. Allows one pipe to be joined to another at a 45° angle.
BMP_FlexBellows "Flexible Bellows" Flexible Bellows — A pair of rigid boards with handles joined by flexible leather sides enclosing an approximately airtight cavity which can be expanded and contracted by operating the handles. Usually fitted with a valve allowing air to fill the cavity when expanded, and with a tube through which the air is forced out in a stream when the cavity is compressed. It has many applications, in particular blowing on a fire to supply it with air.
BMP_RigidCoupling Default Rigid Coupling — The Victaulic® rigid coupling provides rigid pipe joint designed to restrict axial or angular movement.
Flanges - Unions 
BMP_FlangeBlind "Blind Flange" Blind Flange — Blind flanges do not have a bore and are used to shut off a piping system or vassal opening. Its design permits easy access to vassal or piping system for inspection purpose.
BMP_FlangeSlipOn "SlipOn Flange" Slip On Flange — Slip On flanges are slipped over the pipe and then welded from both inside and outside to provide sufficient strength and prevent leakage.
BMP_FlangeWeldNeck "Weld Neck Flange"

Weld Neck Flange — A short cylindrical component used to seal and reinforce the connection between a fitting and a conductor. A flange fits around the conductor and is held in place by clamps.

Weld Neck Flanges are designed to be joined to a piping system by butt welding

BMP_Gasket Gasket Gasket — Gaskets are used for sealing of flange joints, and they are not be reused.
BMP_UnionSA "Default" Union SA — A self aligning double spherical seats union provides a pressure tight joint without the use of gaskets or washers.
BMP_MaleFemaleUnion "Default" Male Female Union — A standard union consisting of a nut, a female end, and a male end. When the female and male ends are joined, the nuts then provide the necessary pressure to seal the joint, acts as a reversible coupling.
BMP_HexagonalBush "HexagonalBush" Bush/Nipple — A hexagonal plumbing bush/nipple and octagonal nipple for use as piping couplers and join two pipes of different diameter.

A small section of pipe of varying length used to connect fluid components

BMP_Socket "Default" Parallel Thread Socket — Parallel/Taper Thread socket provides a coupling with full thread.
BMP_DieElectricUnion "Default" Die Electric Union — These unions are designed to be installed between pipe made from dissimilar metals to prevent accelerated corrosion and deterioration in the piping system due to galvanic and stray current.

A dielectric union breaks the electric current path with a plastic liner between two halves of the union, thus limiting galvanic corrosion.

Sanitary Fittings
BMP_Ptrap "P-Trap With Heel" P-Trap with Heel — A sink trap formed with a bend attached with a low heel inlet usually installed under most house sinks suitable for waste water systems.
BMP_Ptrap1 "Default Ptrap" P-Trap — drain-waste-vent (DWV) fitting, addition of a 90° fitting on the outlet side of a U-bend, thereby creating a P-like shape.
BMP_PtrapGully "PtrapGully" Ptrap Gully — A round gully having a trapped receptacle at surface level that waste or storm water can pass through easily but gases, odors and rodents from the drainage and sewer system can not pass back the other way.
BMP_SPtrap S-PTrap S P-Trap — An S-shaped trap is also known as the S-bend. The fitting incorporates U-bend used to prevent sewer gases from entering buildings.
BMP_SanitaryCross "SanitaryCross" Sanitary Cross — Similar to a cross. This fitting differs from a standard cross in that two of the ports have curved inlets. The fitting has been used in the past for connecting the drains of back-to-back fixtures (such as back-to-back bathroom sinks).
BMP_SanitaryTee "Sanitary Tee" Sanitary Tee — A sanitary tee is a tee with a curved center section. In drainage systems it is primarily used to connect horizontal drains (including fixture trap arms) to vertical drains. The center connection is generally connected to the pipe which leads to a trap (the trap arm). Sanitary tees are supported by the Apply Slope tool. When sloped, the sanitary tee's "Angle" property is automatically calculated.
BMP_RoundCleanout "Round Cleanout" Floor Drain — A floor drain is installed in the floor of a structure, mainly designed to remove any standing water near it. It has gratings that are made of metal or plastic, and a smooth strainer secured over it.
BMP_Plug "Plug" Plug (BeadedSolid/Solid/Hallow/Countersunk) — A solid/beaded solid/hallow/countersunk pipe plug fitting to close the end of a pipe. A plug usually has male threads.
