Order custom gaskets from samples through Gasketech when standard parts are unavailable. Submit dimensions and operating details for review.
Custom gaskets from samples are replacement sealing components produced by using an existing gasket as a dimensional reference. They may suit obsolete, imported or unsupported machinery where an original replacement part is no longer available.
A sample can reveal the required shape, openings and bolt-hole positions. It cannot confirm the correct material or operating limits on its own, which makes accurate service information essential.
What Can an Existing Gasket Sample Show?
An original gasket may retain enough detail to establish its outer profile, internal cut-outs and hole arrangement. Gasketech lists made-to-measure production from drawings or samples through its custom gasket service.
Minor tears may still allow assessment, but stretching, shrinkage, heat damage or missing sections can reduce dimensional accuracy. A drawing, manual, part number or second sample may help clarify uncertain features. Avoid trimming or repairing the gasket, and pack all sections together against firm backing to prevent further damage.
What Information Should Accompany Custom Gaskets from Samples?
A replacement enquiry should explain where the gasket sits and what conditions it faces. These details allow the profile and proposed material to be considered together.
Include the following information:
- Identify the machine, pump, valve, housing or assembly.
- State the liquid, gas, oil or chemical that contacts the gasket.
- Record normal and maximum temperatures and pressures.
- Confirm the original thickness where reliable information exists.
- Note the flange type, surface condition and bolt arrangement.
- Include the required quantity and preferred delivery date.
- Attach drawings, photographs, manuals or part numbers where available.
Machinery must also be isolated correctly before a sample is removed. The WorkSafe Victoria machinery isolation checklist outlines shutdown, energy isolation, lockout and testing considerations for maintenance activities.
How Is a Suitable Gasket Material Assessed?
Matching the old gasket’s outline does not confirm its material was suitable, especially if operating conditions have changed. Material assessment should consider fluid compatibility, temperature, pressure, compressibility and environmental exposure. Gasketech lists compressed non-asbestos fibre, graphite composites, PTFE, rubbers, polyurethane, felt, cork and vulcanised fibre.
No single sheet material suits every sealing duty. Marine applications require careful assessment of the contained fluid and operating limits, while HVAC gasket replacements must account for temperature changes, pressure and system conditions. These factors are also central to specifying custom marine gasket material guide for fuel, cooling and water systems.
Our company background also identifies local and imported machinery among the applications considered. Final suitability still depends on the submitted specifications and joint conditions.
Can Damaged Custom Gaskets from Samples Be Reproduced?
Production may remain possible if enough of the original geometry can be verified. A distorted or incomplete sample may require additional measurements, a mating-component reference or a technical drawing before feasibility can be confirmed.
A replacement gasket cannot correct warped flanges, damaged mating surfaces, incorrect bolt loading or equipment operating outside its design limits. Gasketech also stocks ring and full-face gasket sizes that may suit standard flange applications.

Custom gaskets from samples can provide a practical replacement path for unavailable parts, provided the sample and operating data are adequate. Clear information reduces uncertainty around dimensions, materials and production feasibility.
