At Sealtech, we specialise in manufacturing any custom gasket to suit your exact requirements — even for obsolete machinery, discontinued equipment, or urgent breakdown situations.

Whether you have an emergency shutdown or need a replacement for hard-to-find parts, we offer a fast and reliable solution:

• On-site measurement & design: We can visit your site to measure the application and design the gasket for you.
• Reverse engineering: Simply send us the old or worn gasket (or a sample/photo with dimensions), and we will accurately replicate it.
• No minimum order: Ideal for one-off emergency replacements or small urgent quantities.
• Fast turnaround: From measurement to delivery in the shortest possible time to minimise your downtime.
