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)
Guarnitec rod-side profiles, listed in the order they appear in the complete catalogue. Materials, pressure and speed limits are taken directly from the Guarnitec technical data pages.

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.
