Specify custom sealing washers in Australia with the right material for the job. Gasketech makes washers from your drawing or sample.
Matching a washer’s size is only half the job. Custom sealing washers in Australia also need a material that suits the fluid, temperature, pressure, movement and mating surfaces they will face. Getting the material wrong can lead to a seal that leaks, hardens or loses compression.
Which Material Suits Custom Sealing Washers in Australia?
No material is best across every fluid, temperature and assembly. Gasketech manufactures gaskets, sealing washers, extrusions and mouldings, and our custom gaskets page lists the sheet materials we work with.
These are the main groups:
- Rubber: Natural and synthetic rubber, including Viton.
- PTFE: Virgin, filled and expanded grades.
- Compressed fibre and composites: Non-asbestos compressed fibre, graphite and Kevlar, and graphite and stainless steel.
- Plastics: Polyurethane and other engineering plastics.
- Other materials: Felt, cork, insertion rubber and vulcanised fibre.
Each group has different strengths, and each grade within it behaves differently. We do not publish temperature or chemical limits here, because they depend on the exact compound and the manufacturer’s data.
What Does the Service Fluid Change?
Chemical contact can make an unsuitable washer swell, soften, harden or lose its compression. Temperature cycling and rough sealing surfaces add further stress. Start with the safety data sheet for the fluid. Safe Work Australia’s code of practice for hazardous chemicals says businesses should obtain the safety data sheet from the supplier before a chemical is used, and that it covers safe handling and storage.
Surface condition and the assembly matter as well. A washer sits between mating surfaces, so flatness, finish and clamping load all affect how well it seals. Say whether the joint sees weather, vibration or movement, and avoid choosing by price alone. A cheaper material that fails early can cost more in downtime than the right one.
That information gives a better starting point for any enquiry about custom sealing washers in Australia, because it names what the washer will actually touch.
What Should You Send with an Enquiry?
Clear details cut down on revisions and unsuitable substitutes. Gasketech makes washers to measure from drawings or samples, so send what you have:
- Dimensions: Inner diameter, outer diameter and thickness, plus any tolerances.
- Quantity: We can run any quantity job.
- Profile: Any unusual shape, hole pattern or surface constraint.
- Service details: The fluid, its concentration, normal and peak temperatures, pressure and movement.
- Documents: Any certificates you need. Our custom gaskets page says certificates of approval are available on request.
Gasketech is based in Port Melbourne and delivers Australia-wide by overnight airbag or courier. A dimensioned drawing is the clearest reference, though a sample can work where no drawing exists. For an unusual design, you may want a small trial run first. You would need to set the test conditions and the pass criteria, because only you know the duty.
Specify the Right Washer for the Job
For custom sealing washers in Australia, send us your drawing or sample, quantity and operating conditions so we can discuss suitable materials and dimensions. Enquire through our contact page or call us. For more on preparing your enquiry, read our guide to replacement gaskets from drawings or samples.
