Why Lianseal

Built around the actual sealing problem

Packing fails for predictable reasons: wrong grade, wrong size, wrong installation. We work on those three.

Factory direct

We braid in-house in Zibo, so you buy from the producer, not from a trading layer.

Custom cross-sections

Square braid from 3 mm to 50 mm, custom lengths and die-formed rings.

Technical support

Send media, temperature and shaft speed — we recommend the grade that holds.

Export packaging

Rolls, cartons and pallets prepared for sea freight with neutral or branded labels.

Quality control

From yarn to export carton

Every order passes the same four checkpoints before it leaves the workshop.

01

Yarn selection

PTFE, graphite, aramid or composite yarn chosen for the media and temperature.

02

Braiding

Square braid with controlled tension, then impregnation and lubrication.

03

Dimensional check

Cross-section and length verified against the order specification.

04

Packing & dispatch

Rolled, labelled and packed for export, with documents prepared for customs.

Applications

Where our products are used

Selected by material family according to media, temperature and shaft speed.

01

Pumps

Centrifugal, slurry and process pumps — PTFE and aramid grades for chemical and abrasive service.

02

Valves

Stem sealing for gate, globe and control valves, including high-temperature steam duty.

03

Chemical & petrochemical

Reactors, agitators, heat exchangers and flanges handling aggressive media.

04

Power generation

Graphite packing for high-pressure steam, hot water and thermal circuits.

05

Steel & metallurgy

High-temperature sealing on furnace, rolling mill and gas handling equipment.

06

Marine

Stern tube, pump and valve packing for shipyards and ship repair yards.

PTFE packing rolls
Supply

One producer, from yarn to finished roll

Braiding, impregnation, lubrication, sizing and packing all happen in the same workshop. That means we can hold tolerances, run small custom batches and keep lead times short.

FAQ

Common questions

What information do you need to quote?

Media (water, steam, chemical, slurry), operating temperature, pressure, shaft or stem diameter, cross-section size and quantity. If you already use a packing grade, tell us the name and we will match it.

Can you supply custom sizes?

Yes. Square braid is produced from 3 mm up to 50 mm, in custom roll lengths. Die-formed rings can be supplied to drawing.

Do you supply samples?

Samples of standard cross-sections can be arranged for evaluation. Please contact us with the intended application.

How is the packing packed for export?

Standard packing is 5 kg or 10 kg per roll, then cartons on pallets. Neutral labels are available if you sell under your own brand.

Need a quotation or a data sheet?

Send the media, temperature, pressure and shaft size — we will recommend the right grade and price it.
