Middle connectors

HDPE Pipe middle connectors are the irrigation tools use in connecting the same irrigation pipes. This because Hdpe pipes come in various lengths of 100 meters, 50 meters and so on which limits application lengths beyond the standard one.

Whenever supply requires pipes of longer lengths beyond the above mentioned lengths, automatically there is need to join them together thus the use of Hdpe  connectors

PE pipe middle connector

More ever, Hdpe pipe  connectors come in different sizes according to the pipe diameters. The various sizes available are the 16mm, 20 mm, 25 mm, 32 mm, 40 mm, 50 mm, 63 mm, and 90 mm

Eunidrip irrigation systems stock the above connectors which are relatively cheap and easy to fix unlike the heavy commercial joiners that are available in the market.

Types of Hdpe pipe middle connectors

  1. Butt fusion
  2. Thermal bushing
  3. Electro fusion
  4. Flange
  5. Extrusion
  6. Bolting
  7. Rubber gasket latching

For ease in  Hdpe pipe connection at  relatively cheap Hdpe pipe middle connectors, Eunidrip irrigation systems stocks the middle connectors that use the principles of rubber gasket latching.

In rubber gasket latching the connectors are of different sections which includes the gripper, fastener, rubber seal (o ring), and the holder.

Functions of Hdpe pipe middle connectors parts

Gripper of middle connectors

This is the section with serrated grip like structures which hold together the pipe after fixing.


This is the section that slides into pipe thus pushing the o rings towards the holders so that the pipe leakages are prevented.

Rubber seal (o ring) of middle connector

.Fixing o the pipe correctly and tightly is normally done by o ring


This is the section where the pipes junctions meet

Hdpe middle connectors come in various colors which may include, red, yellow, blue, black and some come with purple color. Colors do not affect the functionality of the tool but it helps in identifying the manufacturers or the batch details.

Procedures in installation of pipe middle connectors  

  1. Cut the pipe at the place to be joined to the axis and clean the pipe ends.

Clean any debris from the pipe.

  1. Prepare the fittings in place and check the connector in terms of the cleanliness, available of rubbers and fasteners.
  2. Place the two simple ends of the pipe placed inside couplings or accessories, so that the two pipes are in content with the central holder.
  3. The connection system should remain in straight position for full attachment.               

Importance of Hdpe middle connectors

  • Green environmental protection 

    non-toxic, tasteless, after strict health monitoring, belongs to green building materials, never scale, can effectively improve water quality.

  • Corrosion resistance

    pipe middle connectors are resistant to corrosion by a variety of chemical, and chemicals present in the soil do not cause any degradation or damage to the pipeline.

  • High toughness

    the material used in manufactured of HDPE middle connectors of irrigation pipes is generally hard and intact. For the uneven settlement, its adaptability is very strong and the seismic performance is good. Hence it brings about a high toughness

  • Crack resistance

    : It has high propagation system for piping usually has some adhesive factors, which has high crack resistance which harden the material help to avoid the breaking of the pipe

  • Good wear resistance

    The HDPE pipe connectors have good wear resistance, low wall friction coefficient, low flow resistance flexibility and strong conveying capacity which enable free wear resistance

  • Excellent 

    The HDPE irrigation pipe can be used in a variety of trench less ways, easy to construction and installation at the field, which it’s the best

  • Low cost

    The HDPE pipe for irrigation has a Low system cost and low maintenance cost can greatly reduce project costs.

  • Long service life

    The buried irrigation pipe is normally used for 55 years, which usually gives long time service

  • Recyclable, environmentally friendly

    The HDPE irrigation pipe connector and materials can be reused, fully in line with the nationally advocated efficient environmental protection concept. Where that its environmentally friendly, and recyclable which it’s Eco-friendly

 Cost of HDPE pipe middle connectors

Joining of the Hdpe pest in dependent on the cost of the middle connectors size . As stated earlier the sizes readily available in the market are 16mm, 20 mm, 25 mm, 32 mm, 40 mm, 50 mm, 63 mm, and 90 mm

The cost of this HDPE middle connectors ranges between ksh 25 to ksh 3500
