Filters & O Rings

Finding the right o ring size is super important for a perfect, leak-proof seal! It’s actually pretty straightforward. You’ll need to measure three key dimensions: the inside diameter (ID), the outside diameter (OD), and the cross-section (CS), which is the thickness of the ring itself. The most crucial of these are the ID and the CS. Once you have these measurements, you can easily find a replacement o ring that matches.

If your old o-ring is stretched or broken, it can be tricky to get an accurate measurement. In that case, it’s best to measure the groove where the o-ring sits. You’ll want an o-ring with an inside diameter that is slightly smaller than the groove’s diameter to ensure a snug fit. Getting the material right, like Viton or Buna, is also vital for chemical compatibility and temperature resistance

Using a high-quality o ring is one of the smartest, simplest things you can do to protect your gear! It might just be a small rubber circle, but it's a critical component that creates a perfect, high-pressure seal between fittings. A top-quality o ring, made from durable materials like Viton, prevents those annoying and costly leaks that can reduce your machine's pressure and efficiency. Think about it - every drop of water that leaks out is pressure and performance lost!

More importantly, a robust o ring is your first line of defence against catastrophic failure. A cheap, poorly made seal can burst under the intense pressure of a commercial-grade machine, potentially damaging expensive components like your gun, wand, or even the pump itself. Investing in the right o ring for the job ensures chemical resistance and temperature stability, giving you peace of mind and saving you from costly downtime.

Regularly cleaning and replacing your pressure washer's filters is one of the most important maintenance jobs you can do. Think of the water filter on your machine's inlet as a bodyguard for the pump. It catches all the tiny bits of sand, sediment, and debris that can come from your water source. Without a clean, functioning filter, those abrasive particles get sucked straight into the pump, causing rapid wear and tear on precious internal components like seals, pistons, and valves.

A clogged filter also starves your pump of water, which can cause it to overheat and run inefficiently, leading to a noticeable drop in pressure and performance. It’s a super simple check that can save you from a very costly pump replacement down the line! Making it a habit to inspect and clean your inlet filter before each use is a pro move that will keep your machine running strong.

Choosing the correct filters for your pressure washer is a fantastic way to ensure it runs efficiently and stays protected! The main thing you need to consider is the 'mesh' or 'micron' size of the filter element. This number tells you how fine the filter is and the size of particles it can trap. A standard inlet water filter is typically around 80-100 mesh, which is perfect for catching common sediment and debris from a mains water supply.

You also need to think about your fittings. Ensure the filter has the correct inlet and outlet connection types and sizes to match your hose and pump. Most professional setups use standard BSP or garden hose fittings, making it easy to find a match. Using the right filter is a simple, low-cost investment that prevents abrasive particles from entering your pump, which can cause significant damage to the valves and seals. A clean, correctly sized filter ensures optimal water flow and protects your machine's critical components.
