THE 18999 VERSATILE SEAL - Used with the Quick TeeJet system.

THE 18999 VERSATILE SEAL - Used with the Quick TeeJet system.

From the pictures you can see how this seal fits over the small filters and nozzle-tip cores.    Pay special attention to the design. The one shoulder is square and the other is rounded. The rounded shoulder faces the outlet.

The seal is used with the Quick TeeJet system.

In the real world, the chances of losing a filter in-field are pretty good when using the standard gasket - 19438. If the 18999 seal is used with the filter it cannot be lost. Why? Because the Quickjet cap must have a gasket or seal for a water-tight fit.

Here's a pic of a split-eyelet body, 100 mesh filter with 18999 seal,air induction Twinjet tip and cap.

TRIGGERJET 50800 - Standard or modified the choice is yours

TRIGGERJET 50800 - A more versatile modified lance.

Virtually everywhere you look retail outlets are nothing but Chinese trading posts. Complete knapsacks are being offered at prices as low as $18. (about R200) Quality leaves much to be desired but there is little doubt that they sell in there thousands. Fortunately, there are serious clients who have learned their lesson and still buy quality.

This picture shows you the type of lance nozzle arrangement supplied from the east. The thread size is metric which is the way the world is heading. The problem is that it can't be adapted and no nozzle-tips fit the caps.

Here's a picture of the 50800 Triggerjet lance manufactured in China. If the specs are adhered to the product is still good. It is not the aim of this blog to get involved with the failed financial system.

The adjustable Conejet supplied with the Triggerjet is suitable for the domestic market and specifically for use with insecticides, fungicides and foliar feeds. For example an orchid grower with a few hundred plants wants a fine spray for foliar feeding. Perfect.

For the majority of our clients we modify the lance nozzle assembly to make it more versatile.

Spares? We keep a supply of the inlet hose-shank to fit a 9.5 mm ID or 3/8th hose. Note the filter fitted in the trigger handle.

What happens when the the trigger leaks? Can it be repaired?

YES!  This need not be  a "gooi weg koop nuwe!"
