What types of brass press fittings are available (e.g., elbows, tees, couplings)?

Introduction to the product family
Brass press fittings come in many shapes. Each shape serves a specific plumbing need. They connect, redirect, or terminate pipes. Example: a full system uses elbows, tees, and couplings.

Straight couplings (the basic connector)
A coupling joins two pipes in a straight line. It has two identical pressing ends. Brass press fittings include this simplest type. Example: repairing a burst pipe by adding a new section.

Reducing couplings (for different sizes)
One end fits a larger pipe diameter. The other end fits a smaller pipe. Brass press fittings allow size transitions without adapters. Example: connecting a 22mm main to a 15mm branch line.

90° elbows (changing direction)
These fittings turn the pipe by 90 degrees. They are the most common directional fitting. Brass press fittings offer both female and male versions. Example: going from a wall pipe to a floor-mounted toilet.

45° elbows (gentle turns)
These fittings turn the pipe by 45 degrees. They create smoother flow than 90° elbows. Brass press fittings include this option for low-pressure loss. Example: routing pipes around a corner in a mechanical room.

Equal tees (splitting flow)
A tee has one inlet and two outlets. All three ends have the same diameter. Brass press fittings use tees for branch lines. Example: feeding two sinks from one main water line.

Reducing tees (unequal branches)
The run (straight) may be one size. The branch (side) may be a smaller size. Brass press fittings offer many reducing combinations. Example: a 22mm main with a 15mm branch to a dishwasher.

Cross fittings (four-way connection)
A cross has four openings in a plus shape. It is less common than tees. Brass press fittings include crosses for complex layouts. Example: a manifold feeding four appliances from one point.

Couplings with female threads
One end presses onto a pipe. The other end has internal threads. Brass press fittings connect to threaded valves or fixtures. Example: attaching a press elbow to a threaded hose bib.

Couplings with male threads
One end presses onto a pipe. The other end has external threads. Brass press fittings allow connection to female-threaded parts. Example: joining a press tee to a threaded brass gate valve.

Example: residential water distribution
A house needs water for kitchen, bath, and laundry. Brass press fittings create the network. Elbows turn corners at walls. Tees split to different rooms. Couplings join pipe lengths. Example: a typical house uses 30-50 press fittings.

Example: hydronic heating system
Radiant floor heating requires many branches. A manifold sends hot water to loops. Brass press fittings include special manifold adapters. Elbows turn pipes up from the floor. Example: a 200 m² house uses 80+ press fittings.

Termination fittings (end caps)
A cap seals the end of a pipe permanently. It is used for future connections. Brass press fittings also offer end caps for testing. Example: capping a pipe during pressure testing before final hookup.

Final summary of types
Brass press fittings come in over 20 basic types. Couplings join pipes straight. Elbows turn corners at 45° or 90°. Tees split flow equally or unequally. Crosses distribute to four directions. Threaded versions connect to fixtures. Caps seal pipe ends permanently. Reducing types change diameters. Every plumbing layout has a fitting solution. Example: a professional plumber stocks 50+ different press fittings in the truck.
