Compare the published product scope and source details, then include your specifications and quantity in an enquiry.
Manufacturer profiles associated with Sealing Edge.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Regular visual inspection for deformation/cracks, torque verification during reassembly, and replacement every 2-5 years depending on operating cycles. Clean with isopropyl alcohol only.
Not recommended due to compression set and potential surface damage. Always replace during major maintenance unless manufacturer specifies reusability.
Aluminum expands/contracts with temperature changes (α≈23×10⁻⁶/°C). Design must account for thermal cycling to maintain compression without over-stressing components.
