Available Pipe Fitting And Connection Types

Pipe fittings and valves are key to the success of many industrial and residential applications. They connect, redirect, and control flow in many applications.

From various shapes to multiple sizes, the right choice is key to efficiency and functionality. Need the perfect fit? We have it. Here’s a look at our selection.

Fittings Types

Elbows: Used to shift the pipe’s direction, elbows are available in angles including 90°, 45°, and 180°, with both short and long radius. They are commonly found in plumbing systems where the flow direction needs to be changed.

Tees: Tees may be equal, reducing, or double-tapped, and are used to separate or combine the flow of a piping system. Equal tees have the same size for all three ends while reducing tees connect different-sized pipes.

Couplings: These are used to join two pipe sections together, allowing for a continuous flow. Couplings come in different sizes to match the pipes being connected.

Unions: Unions allow easy connection and detachment of two pipe segments, allowing for easy maintenance and repairs without dismantling the whole system.

Caps: Used to seal a pipe’s ends, caps are often employed during system tests or when sections are temporarily shut off.

Plugs: Similar to caps, plugs are also used to seal a pipe or fitting’s end, providing a leak-proof closure.

Nipples: Small bits of pipe that join fittings together, nipples can vary in length and are often used in hose connections.

Adapters: Employed to join various pipe and fitting types, adapters ensure compatibility between different components.

Flanges: Flanges come in three main types: slip-on, weld-neck, and lap-joint. They are used to connect pieces of pipe or fittings together, and each type has specific applications, such as slip-on for easy installation, weld-neck for high-pressure systems, and lap-joint for flexibility.

Connection Types

Threaded: The most common type, where the fittings are screwed together. Threaded connections are often used for small to medium-sized pipes and in low-pressure applications.

Welded: Welded fittings are permanently joined by welding, providing a strong and leak-proof connection. They are typically found in industrial environments where high-pressure handling is required.

Flanged: Flanged connections utilize a bolt to connect and are often employed in large systems where regular maintenance is needed, allowing for easy disassembly.

Press-fit: Press-fit connections are made by pressing or adhering fittings together, usually with a special tool. These are commonly used in modern plumbing systems for a quick and secure connection.

H3: Available Sizes and Schedules

Sizes: Range from 1/2” – 36” STD, XH, with different sizes suited for various flow volumes and pressures.


  • 20
  • STD
  • True 40
  • 60
  • XH
  • True 80
  • 100
  • 120
  • 160
  • XXH

Schedules refer to the thickness of the pipe wall and are chosen based on the specific requirements of the job, such as pressure, temperature, and flow rate.

Weld Fittings

We offer multiple types of weld fittings, including:

  • LR 90’s
  • SR 90’s
  • 3R 90’s
  • Red 90’s
  • 45’s
  • Straight Tees
  • Reducing Tees
  • Concentric Reducers
  • Eccentric Reducers
  • Caps
  • LR & SR 180 Deg Return Bends.

Each type serves a unique purpose, such as reducing tees to connect different pipe sizes, or 90-degree elbows for direction change.
