Guarnitec is the Italian sealing house behind the two material brands Sealparts supplies across hydraulic and pneumatic sealing applications: Tecnotex (fabric-reinforced NBR) and Tecnolan (engineered polyurethane). This summary consolidates the profile families, materials and pressure/speed envelopes into a single reference sheet.
The two material brands
| Brand | Material family | Primary use | Signature |
|---|---|---|---|
| Tecnotex | Fabric-reinforced NBR (cotton/polyester + nitrile) | Heavy-duty hydraulic packings, chevron sets, buffer and rod seals | High extrusion resistance, high load capacity |
| Tecnolan | Engineered polyurethane (TPU, cast PU) | Rod & piston seals, wipers, buffers for hydraulic cylinders | Wear resistance, low friction, tight extrusion gap tolerance |
Rod seals (catalogue pp. 16–111)

How to choose between Tecnotex and Tecnolan
- Pick Tecnotex (fabric-reinforced NBR — TSE, TGO, GT/3, GT/5, GT/7, PSE, TLI, TDE, PDE, TGU, TRU) when the application sees severe pressure peaks, wide extrusion gaps or shock loading — fabric reinforcement resists extrusion and blow-by up to 70 MPa.
- Pick Tecnolan (engineered polyurethane — TTS, TTI, TTH, TTX, TTU, TTE, TTE/W, TTQ, TTR, BUFFER, and the GH*/GP*/GGW wipers) for standard industrial and mobile hydraulics where dynamic sealing, low friction and clean stroking matter.
- Pick the Gua-Ring PTFE ranges (serie 01, 02, GIR, GER — Accofluor filled PTFE with an NBR energiser) for high speed (12–15 m/s), rotary or stick-slip-sensitive applications.

Frequently asked questions
- What is the difference between Tecnotex and Tecnolan?
- Tecnotex is fabric-reinforced NBR designed for high extrusion resistance and shock loading (chevron packings, heavy-duty hydraulics). Tecnolan is engineered polyurethane used for standard hydraulic rod, piston and wiper seals where low friction and clean dynamic sealing matter.
- Where can I buy Guarnitec, Tecnotex and Tecnolan seals in the UK?
- Sealparts Ltd supplies the Guarnitec range including Tecnotex and Tecnolan across the UK and Ireland. Send us a part number, sample or groove dimensions for a quotation.
