Heat and pressure will cause the O ring to go brittle, and lose its sealing qualities. When this item has to be removed during a re-build or overhaul, don't be tempted to re-use it, make sure you use a new part very time. To ensure you order all the parts you need to complete your overhaul, check the catalogue that relates to your model, and in many cases we also have an online 'parts list' fiche, which will help pin point all the items you need. The more items you order in one shipment, the more cost effective the shipping costs!
