The checklist that decides the right gasket.
Sealing specialists use the STAMP checklist, adding Speed for pump and valve packings. Share what you know and we will work out the rest with you.
Send us your STAMP details- S
Size
Flange standard, size and PN or Class, or a drawing or sample. For packings: shaft and stuffing box sizes.
- T
Temperature
Normal operating and peak temperatures, and any thermal cycling.
- A
Application
Pipe flange, heat exchanger, pump, valve or boiler, and the flange face and condition.
- M
Media
Exactly what is being sealed, with concentration: water, steam, oil, acid, gas or oxygen.
- P
Pressure
Working and test pressure, and vacuum if applicable.
- S
Speed (packings)
Shaft speed, and whether the duty is rotary or reciprocating.
Choosing a material
Which gasket material suits your joint?
| Material | Choose it for | Examples in the range |
|---|---|---|
| Compressed fibre sheet | General water, steam, oils, fuels and gases | KLINGERSIL® C-4400, Novus 34 |
| PTFE | Aggressive chemicals across the pH range; low bolt-load or glass-lined flanges | Novus Uniflon 50, 51, 53 |
| Graphite | High temperature and thermal cycling | Novus 49 Graftec, Maxigraph |
| Spiral wound & kammprofile | High pressure and temperature, heat exchangers, difficult flanges | Metaflex, Maxiprofile |
| Cork & cork-rubber | Light loads, uneven faces and anti-vibration | KLINGERSIL® C-4106, cork sheeting |
| Compression packing | Pump shafts and valve stems | Klinger 3222 graphite, 54F PTFE |
Compressed fibre sheet ratings depend on thickness: thinner gaskets generally handle higher temperatures and pressures. Maximum temperature and pressure do not apply together, so tell us your conditions and we will confirm the grade.

Questions
Frequently asked.
What do you need to quote a gasket?
The flange standard and size (for example DN100 PN16, or 4" Class 150), or a drawing or sample; full face or ring; plus the media, temperature, pressure, thickness and quantity.
Can you supply gaskets cut to my drawing or sample?
Yes. Send a DXF or PDF drawing, dimensions or a sample and we will supply gaskets cut to it in the material your joint needs.
Which gasket material should I use?
It depends on the media, temperature, pressure and flange condition. Compressed fibre suits general service, PTFE aggressive chemicals, graphite high temperatures, and spiral wound or kammprofile high pressure and cycling. Send us the conditions and we will recommend a grade and thickness.
Why does gasket thickness matter?
With compressed fibre sheet, thinner gaskets generally handle higher temperatures and pressures. Use the thinnest gasket the flange condition allows, commonly 1.5 mm or 2 mm, going thicker only for uneven flanges.
Do you have WRAS-approved or food-safe materials?
Yes. WRAS-listed jointing sheet grades such as Novus 34 and KLINGERSIL® C-4430 are available, and PTFE grades suit food and pharmaceutical service. Tell us the application so we can check the approval covers it.
Can you supply spiral wound gaskets?
Yes. Spiral wound gaskets are available to ASME B16.20 and EN 1514-2, in a choice of winding metals and graphite, PTFE or mica fillers, with inner and outer rings as required.
Which packing do I need for my pump or valve?
Tell us the equipment, shaft or stem diameter and stuffing box bore, the media, temperature, pressure and shaft speed. Packings are rated for maximum temperature, pressure and speed, but not all three at once.
What about minimum orders, lead times and certificates?
Everything is supplied to order, from a single gasket to production runs, with lead times on your quote. Certificates of conformity and manufacturer data sheets are available on request.
