HUBLESS JOINT |
|
A joint usually for copper tubing but is sometime used for plastic tubing |
FLARED JOINT |
|
One pipe slips within another, common dor fixture traps and drains |
SLIP JOINT |
|
Inserting rubber gaskets into sleeves, for straight pipe connections |
RUBBER RING JOINT |
|
A joint bet. threaded pipe or bet. a threaded pipe and threaded fitting, such BI,GI,uPVC |
THREADED JOINT |
|
Angular fitting used to change the direction of a supply pipe. Also known as E11 |
ELBOW |
|
A type of elbow that has female fitting on one side a male fitting on the other end |
STREET ELBOW |
|
Has a straight through portion and a 90 degree takeoff on one side. Three opening are same size |
STRAIGHT TEE |
|
Has two ends tha same and one end smaller |
REDUCING TEE |
|
Designed w/ a slight curve in the 90 degree transition so as to channel flow from a branch line toward the direction of the main flow |
SANITARY TEE |
|
A bell end tee which has a branch that is tapped to receive a threaded pipe fitting or threaded pipe |
TAPPED TEE |
|
Used to join straight runs of pipe |
COUPLING |
|
A coupling used to connect a smaller pipe to larger one, vice versa |
REDUCER/INCREASE |
|
Pipe adapter is a fitting that is used to connect pipes of different materials or pipes that require different joining methods |
ADAPTERS |
|
A fitting which is threaded on both the inside and outside. |
BUSHING |
|
A replacement to reduce an opening of a ditting or pipe without the use of a conventional reducer |
BUSHING REDUCER |
|
Used to connect the ends of two pipes, neither of which can be turned |
UNION PATENTE |
|
Connects four pipes together |
CROSS |
|
An economical, practical and reliable alternative to welded and screwed systems |
FLANGE UNION |
|
A threaded pipe fitting with male threads use to close the end of a ferrule or a pipe having female threads |
PLUG |
|
A fitting with a female (inside) thread. |
CAP |
|
A short piece of pipe (not a fitting) |
NIPPLE |
|
An offset means a combination of pipes and/ or fittings that brings one section of the pipe out of line but into a line, parallel with the other section |
OFFSET BEND |
|
A pipe fitting or a preformed piece of tubing which provides a 180 degree change in direction |
RETURN BEND |
|
A threaded stem raises and lowers a wedge shaped disk, which fits against a smooth machined surface within the valve body Also known as full way valve |
GATE VALVES |
|
Used to control flow by means of a circular disk that is compressed against a valve seat surrounding the opening through which water flow Also known as compression valve |
Globe valve |
|
A globe valve in which the inlet and outlet are at 90 degrees to each other |
ANGLE VALVE |
|
A valve in which the flow is controlled by a ball that fits tightly against a resilient seat in the valve body |
Ball valve |
