Chemical products often comprise of many different chemicals which can effect the component materials of the sprayer/dispenser (e.g. swelling or corrosion). The concentration of these chemicals and the temperature can give different results. Time is another factor – a component may not show any reaction used many times in a short period but can show a reaction when used a few times over a long period. How long do you need the sprayer/dispenser to last? 1 day? 1 week? 6 months? We can therefore, only advise as to whether our products are suitable for use with general chemical components and recommend you carry out trials to ensure compatibility with your own formulation.

Ask your supplier if they can provide a Safety Data Sheet. It should show a list of the main chemical components with the concentrations expressed as a percentage. This will help us to give you advice.

This depends on what chemicals you are spraying. Flourocarbon (trade name Viton) is the best overall resistant material to the widest range of chemicals. However, it is more expensive than other materials and may not be necessary. Nitrile (or Buna N) is lower in cost and is suitable for many water based chemicals. Ask our staff for more information about your chemicals.

Actual capacity is the ‘total’ capacity of the container. However, the pressure sprayer needs an amount of air to compress, to force the chemical out. The working capacity is the maximum amount of product which can be filled to operate the sprayer.

To get the best results from your sprayers we recommend they are completely emptied and rinsed through after each use.

The standard Trigger Sprayers have a 28mm diameter cap with two different heights – Deep (28/410) and Shallow or Short (28/400). In the UK, the most common size for the retail market or Ready to Use (RTU) pack is the 28/410. The industrial/re-useable packs tend to have the 28/400 caps. These references correspond to the necks on the bottle so your bottle manufacturer can confirm what neck is on their bottle.

Trigger sprayers are notorious for ‘backing-off’. The vibration of being ‘in transit’, loosens the cap and leakage can occur. The answer is to have a suitable neck on the bottle – one that suits the trigger cap and if possible, has an anti-back off system in the thread. An anti-back off system has extra pieces in the thread – either a twin thread, vertical pieces or a series of ‘lugs’ around the neck that gives resistance to the cap vibrating loose.

For easy priming of long tube sprayers, hold the sprayer at the same level of the liquid until it is primed.

Steel containers generally have a 3/4″ and/or 2″BSP (British Standard Pipe) or fine thread. It is very difficult to produce plastic containers with such a fine thread and so they have more coarse threads. The two most common plastic threads are a 56 x 4 Buttress Thread and the more coarser 70 x 6 Buttress Thread. Most drum pumps will have a ‘standard’ 2” BSP thread and so we supply Drum Adapters to suit both of the Buttress threads above. Containers can have Internal (Female) threads (as above) or External (Male) threads which are sealed with a cap. You can still use a drum pump on these threads with our External Thread Adapter (see Drum Pumps & Adapters).
