What Are 4 mm Barbed Irrigation Fittings And Pipe Fittings?

If you use 4 mm irrigation fittings and pipework, you'll want an easy method of directing and splitting water flows. This is where you'll want 4 mm Barbed Irrigation Fittings and Pipe Fittings. By investing in the right 4 mm Barbed Irrigation Fittings and Pipe Fittings Barbed Joiners, you can create a garden watering system with secure, watertight fittings and diversions.

Barbed irrigation fittings securely divert water exactly where you want it. The barbed-end design means the barbed fittings are slightly wider than the barrel of the fitting. This results in a tight, secure connection.

Match Tubing and Pipework With The Corresponding Sized Irrigation Fittings

Using the same gauge Barbed Irrigation fittings and pipework means you can create secure, watertight connections. Using barbed irrigation fittings allows you to divert the flow of nutrients and avoid kinking the pipework. Irrigation fittings allow you to keep runs of pipework in a straight line to maintain flow rates. Using barbed irrigation fittings is an easy way to add additional lines to an existing irrigation system. They allow you to change the direction of water flow, the barbed irrigation fittings have multiple uses.

  • Connect pipework together.
  • Repair damaged pipework
  • Step down the diameter of pipework from 4 mm down to lower diameter dripper feed lines
  • Barbs ensure a tight fit.
  • Made from high-quality plastic.

How Do I Know What Size Of Barbed Joiner Fitting To Buy For My Irrigation Tubing?

The Barbed Cross Irrigation Fittings are measured, based on the barrel's outside diameter dimensions. The outside dimension is also known as the "OD". If you have tubing with a 4 mm inner diameter, also known as the "ID", you'll want to match the tubing inner diameter with the outer diameter of the barbed irrigation fitting. Matching the ID and OD measurements means you'll get a solid, watertight seal.

Why Do I Need Barbed Irrigation Fittings?

Barbed Irrigation fittings allow keen gardeners to water different areas of the garden simultaneously from one water source. This method of watering is cost-effective, efficient and helps to ensure minimal wastage.

How Do I Use Barbed Irrigation Fittings?

To get the best seal with Barbed Irrigation fittings, pour a cup of very hot water and use it to dip the hose in, making it pliable. When warmed, and slightly softened, the supple pipework is easy to push over the barbed irrigation fitting's end. Once cooled and contracted, the pipe should remain securely fitted.

Garden tip: For a totally secure fitting with high pressure systems, fix the hose over the barb with suitable jubilee clips.
