Design

Cylindrical, usually male-threaded at both ends.
Materials vary with the application: galvanised steel, stainless steel, PVC, brass, bronze, etc.
Threads usually to ISO 7-1 (BSP) or ANSI NPT.

Advantages

Quick connection: threaded joints without welding.
Wide compatibility: many thread types and sizes.
Easy repair: quick replacement in case of leaks or damage.
Economical: fast connections at low cost.

Considerations

Thread compatibility matters: choose correctly between standards such as BSP and NPT.
Seal with PTFE tape or a gasket.
Choose the material to suit the application; stainless nipples are recommended for chemicals.
Overtightening can strip threads or crack the nipple; torque-controlled assembly is recommended.

Nipple type	Characteristics	Applications
Hex nipple	Hexagon in the middle for a spanner	Where easy assembly/disassembly is needed
Long nipple	Longer than standard nipples	Deep connections
Welding nipple	Can be welded to the pipe	High-pressure lines
Reducing nipple	Transition between different pipe sizes	Size transitions

PTFE tape

PTFE (Teflon) tape is a thin, flexible sealing tape made of polytetrafluoroethylene. It is widely used on threaded pipe joints to prevent leaks and ensure a tight seal.
