Pure PTFE
Braided construction made from pure PTFE yarn. Fluid compatibility and operating conditions are assessed together for valves and low-speed pump applications.

Braided Gland Packing
PTFE, graphite and aramid braided gland packing options for pumps, valves and process equipment.
The right choice starts with more than the material.
Fluid, motion type and stuffing-box dimensions must be assessed together. Hantech Filter clarifies the braid construction and supply scope using your technical information.
Ten constructions, three material families
PTFE-based packing
Different impregnation and yarn constructions for the fluid and motion involved.
Lubricated pure PTFE
Pure PTFE braid impregnated with lubricant. Lubricant and process-fluid compatibility must be checked for dynamic service. Not suitable for food applications.
Synthetic fibre and PTFE
Filament yarn impregnated with PTFE before and after braiding. Yarn, impregnation and equipment conditions are considered together during selection.
Graphite-filled PTFE
Braided construction combining PTFE yarn and graphite. Assessed using fluid, temperature and sliding-speed information.
Graphite-based packing
Compare pure graphite, PTFE-containing and aramid-corner constructions.
Pure graphite
Construction made from graphite yarn. Medium chemistry, temperature and motion type require separate checks for pump and valve applications.
Graphite with PTFE
Construction using graphite and PTFE yarn with silicone oil. Lubricant compatibility and equipment operating conditions are clarified before quotation.
Graphite with aramid corners
Braid combining graphite-filled PTFE construction with aramid corners. For reciprocating pumps, reactors and mixers, motion and stuffing-box dimensions are assessed together.
Aramid-based packing
Aramid yarn, PTFE impregnation and corner reinforcement represent different constructions.
Pure aramid
Braid made from lubricated pure aramid yarn. Abrasion conditions, shaft surface and fluid properties are checked together during selection.
PTFE- and oil-impregnated aramid
Pure aramid yarn impregnated with PTFE and oil. Product-specific technical confirmation is required for the chemical medium and dynamic operating conditions.
PTFE with aramid corners
Construction braided with pure PTFE edges and aramid corners. The PTFE surface and aramid-corner combination must be verified against the selected product data sheet.
Operating limits are verified for each product
Temperature, pressure and speed limits depend on material, braid and service type, such as a pump or valve. Separate maximum values do not guarantee simultaneous operation at those limits. Final selection is confirmed against the manufacturer data sheet and actual process conditions.
Suitability for food or pharmaceutical processes cannot be established from the material name alone. Required compliance documents, lubricant content and process requirements must be verified for the selected product.
What information is needed for a quotation?
- Equipment type: pump, valve, mixer or reactor; make and model.
- Shaft or stem diameter, stuffing-box bore and available depth.
- Required square cross-section, number of rings or total length; quantity in pieces or kg.
- Fluid identity, concentration, temperature and operating pressure.
- Rotary or reciprocating motion, rotational or sliding speed; solids and abrasion conditions.
- Existing packing photo, failure symptoms and any data-sheet or compliance-document requirements.
