PTFE
PTFE Gland Packings: for chemical and food applications
Chemical resistance: compatible with most aggressive chemicals, both liquid and gaseous (acids, alkalis, solvents, chlorine), ideal for highly corrosive environments.
Low friction coefficient: ensures reduced heat generation, prevents seizing, and minimizes wear on shafts and bushings.
For food and pharmaceutical industries: pure PTFE packings impregnated with inert lubricants compliant with regulations for sensitive processes.
Wide range of temperatures and pressures: reinforced solutions for high pressures, extrusion resistance, and good peripheral speed.

PT 2750/FDA
FDA compliant lubricated PTFE
Made from 100% pure PTFE multifilament yarn impregnated with a PTFE-lubricant. Diagonally braided at medium density, it offers excellent malleability and sealing with minimal tightening loads. Thanks to the special lubricant, it ensures long service life without wear on bushings or shafts.
Applications
Compatible with any aggressive chemical, whether liquid or gaseous. It is primarily used in the food, pharmaceutical, chemical, and drinking water industries.
Certifications
FDA.
Max operating temperature: +280 °C
Min operating temperature: -200 °C
- Chemical industry
- Prevents overheating
- No shaft wear
PT 2750/L
Lubricated PTFE
Packing made of 100% PTFE yarn, yarn-by-yarn impregnated with PTFE lubricant. Diagonally braided in a "soft" execution for better adjustment on centrifugal pumps. Thanks to the additive-enhanced lubricants, it prevents overheating and subsequent burning and wear of the shafts.
Applications
Agitators, reactors, filters, highly aggressive environments. Resists all chemicals (excluding molten alkali metals). Chemical and petrochemical industry, storage plants. Suitable for acids, alkalis, solvents, ketones, and chlorine.
Max operating temperature: +280 °C
Min operating temperature: -150 °C

- Aggressive chemicals
- Flexible
PT 2750/S
Dry PTFE
Braided packing made of 100% pure virgin PTFE yarn, saturated with suspended PTFE. Diagonally braided at high density with a minimal internal core to make it flexible and mechanically resistant while maintaining a perfectly square section.
Applications
Reciprocating machines, piston pumps, dosing pumps up to 200 bar. Low-speed mixers and agitators, valve stems, expansion joints, control valves. Chemical and pharmaceutical industries. Suitable for any aggressive chemical compatible with PTFE.
Max operating temperature: +280 °C
Min operating temperature: -200 °C
- Universal use
- For refineries
- High mechanical strength
