Quality CAT and JCB Hydraulic Seal Kits at Industry Leading Prices

Why do I need Hydraulic Seal Kits?

Pressure seals on hydraulic rams, pumps and motors often develop leaks due to the harsh conditions and high pressures involved. If the leak is not treated, the level of hydraulic oil in the machine would gradually drop as oil leaked, potentially causing damage to other components on the machine.  It is regularly required to rebuild and reseal a hydraulic ram or other component due to hydraulic oil leakage.





Sigma supply high quality seals for earthmoving and construction equipment. Our seals have been used both by manufacturers of construction equipment, and by resealers and ram rebuilders. Our quality is second to none, and our pricing is extremely competitive.

There are 3 factors which place our spare parts above all other seal kit suppliers:

  1. Quality.  SigmaPartFinder hydraulic seal kits resemble the same high specifications as genuine new parts and therefore we guarantee they will fit like new, as would in a brand new machine.
  2. Price.  We can beat all OEM parts in value, while achieving the same performance and quality standards.
  3. Lead Times.  As we have shipping experience with machinery from our parent company, www.sigmaplantfinder.com, we can ensure fast and efficient lead times across all Sigma Parts.
How do I know the part will fit?

To find the exact seal kit for your ram, the best way to do it is to find out the part number you need, and then search it in our search bar on our homepage, www.sigmapartfinder.com.  This will show you the right part for what you need, and you can order quickly and efficiently. If you don't know the seal kit part number, please live chat or contact us and we will help guide you through the process.

We have a huge range of hydraulic seal kits to fit all CAT and JCB excavators.  However, if you can't find the part you need please contact us and we will source it for you.






The Sigma PartFinder Story

You may have dealt with our parent company, Sigma PlantFinder in the past. They are one of the biggest machinery sellers in the world, but their ethos is to ensure the aftersales experience equals the excellent buying experience all Sigma customers love.  Keeping in close contact with the customers to help them with machinery problems in a large part of aftersales, so to improve the experience Sigma started to help customers by supplying them with spare parts, not only machines.  Over time, Sigma began to realise that many machinery users find ordering spare parts just as expensive and difficult as ordering machines.  When Sigma found they could cut out a lot of the difficulty in ordering spare parts, they decided to start a dedicated spare parts company that will further help machinery users around the world.  The spare parts company was duly christened Sigma PartFinder, and we have only grown from there.  We're proud to say our customer's have given us excellent feedback from our very first deals.

From a customer based in Thailand: Shipping process was great. Very fast shipment!

Our 3 Driving Principles:

We are dedicated to making the spare parts ordering process easier.  We do this by focusing on 3 areas, we call them our 3 driving principles.  Our aim is to keep improving each one, knowing that if we achieve that, the PartFinder experience will never stop improving.

1, To take the hassle and time out of ordering spare parts.  Machine downtime always means lost revenue, so getting spare parts faster is crucial for you.  Here at Sigma PartFinder, that's what we do. 

2, Spare Parts is a expensive business.  Not only do you lose revenue when your machines can't work due to mechanical issues, but the spare parts needed can be very expensive.  Using our online ecommerce based method of sales, we can reduce your expenditure on spare parts by up to 60%.

3, We want to consistently be able to offer our customers higher quality spare parts.  All our parts from the OEM supply chain, and we always physically check every single spare part before it leaves our warehouse to make sure it conforms to our quality standards.  This is great, but most importantly it allows you keep your machines running.
