SABS-533 SPECIFICATIONS
Emjay® Barbed Insert fittings are designed for use on polyethylene pipe manufactured to SABS-533 specifications (class 3 or class 6).

SUPERIOR QUALITY:
Emjay® fittings will not increase the pipe diameter by more than 10% as recommended by the South African Bureau of Standards and won’t cause stress cracking.

JOINT STRENGTH:
Emjay® fittings are manufactured with a unique barb configuration which is designed to take maximum advantage of the memory of polyethylene pipe, making it possible for the pipe to return to it’s original size between barbs.

Emjay® black nylon insert fittings:

Emjay® fittings are the best quality fittings to use for an internal connection in the installation of your irrigation system. Emjay® fittings fit inside the polypipe and are designed with a unique barbed configuration that improves the strength of the join with the pipe, ensuring a leakproof connection.

EMJAY®
BARB CONFIGURATION


VS

STANDARD
BARB CONFIGURATION

Emjay® insert fittings are manufactured from top grade nylon raw material and are designed with a a thicker wall section than most fittings in the industry, providing extra strength and durability which allows them maximum resistance to UV.

Emjay® Insert fittings come in a variety of diameters to fit into a range of polypipe diameters. For an installation of Microjet® irrigation systems, we recommend a polypipe with a 20mm diameter to be used. Please use a polypipe manufactured to SABS-533 specifications (class 3 or class 6).

It is recommended that suitable clamps are used on all Emjay® Barbed Insert fittings to prevent fittings blowing out under pressure.

These fittings have been tried and tested for over 35 years in the harsh South African sun and are still going strong.

  • Manufactured from top grade nylon raw material to ensure quality
  • Strong and durable with carbon black for maximum UV protection.
  • Thicker wall section for extra strength and durability.
  • Unique, registered barb design ensures tight, leakproof seal every time!

MB 703 – 20mm x ½”BSP
MB 705 – 25mm x ½”BSP

The Emjay® Insert Female Combination Teepiece is used for fitting a sprinkler, standpipe or other accessory with a male thread to a pipeline. It consists of two barbed “straight” legs with the “crossed” leg being a female BSP thread. An example of its use is for fitting a pop-up sprinkler to a lateral pipeline.

MB 144 – 25mm x 1”BSP
MB 275 – 40mm x 1½”BSP

The Emjay® Insert Male Adaptor (P x MI) is used for connecting a polyethylene pipe to a B.S.P. threaded pipe, fitting or instrument. It has a standard Emjay® barb on one side with a male BSP thread on the other. A common use is as a takeoff from a manual or electric solenoid valve.

FLOW CONTROLS

MBFlowControl-sml print

MB 405 – 15mm
MB 410 – 20mm

The Emjay® Flow Control is a fitting designed for restricting the flow in pipelines especially in undulating conditions where gravity causes an imbalance in operating pressures and this imbalance cannot be controlled by reducing pipe size alone. Designed as a flow control this unit does NOT shut off flow completely and can, therefore, NOT be used as a shut-off valve.

Although this fitting is part of the Emjay® Insert Fittings range it is not made from nylon but rather from ABS which is a tough engineering material.

END PLUGS

MBEndPlug-sml print

MB 138 – 15mm
MB 139 – 20mm
MB 140 – 25mm

The Emjay® Insert End Plug is used to close off the end of a polyethylene pipeline. A popular way to do this is to bend the end of pipe over and then use wire or some other method to tie the two pieces of pipe together thus closing off the end. It is recommended that an End Plug is used instead of this method as the pipe will be weakened from being kinked and may tear or leak. Using an End Plug also gives the installation a much neater finish.

INLINE FILTER

InlineFilterInsertEnds

MB 161 – 20mm – Clear Barrel

This filter is designed specifically for use in a Microjet® irrigation system.  It is meant for use in low volume, low pressure systems only.

The Inline filter has one filter screen (or cartridge) available.  This cartridge is designed to trap any particles that would clog up a standard Microjet®.  The openings in the inline filter cartridge are 1.3mm x 0.5mm which equates approximately to a 20 mesh filter screen in area of opening (0.65mm2).  The smallest Microjet® is a black base which has an orifice size of 0.8mm, so this filter would work perfectly on any Microjet® System.

The Emjay® Inline filter is available with Emjay® Insert (barbed) ends in 15mm and 20mm.  These ends conform to the rest of the Emjay® range of fittings with their unique barb configuration.

The Emjay Inline filter comes with a clear barrel (body), allowing one to easily see when the filter cartridge needs cleaning or is blocked.

SNAP-ON®

IMG_8013

PN105 for ½” Hose – or Polypipe
PN106 for ¾” Hose – or Polypipe​

The Snap-on® / Emjay® Hose Connector is designed for use with either a hosepipe or polypipe. It is a more permanent connection and is ideal for use where the pressure in the pipe can build up. This happens when the hose nozzle at the other end of the hose is closed off and the hose pressure builds up to mains pressure. In this situation, the standard Hose Connector could blow off and it is better to use this connector with a hose clamp.
It is available in ½” (15mm) and ¾” (20mm) fitting.
