MACHINED SEALS

CNC Turning Seals

Lathe-cut precision seals with no mold cost — PTFE, PU, NBR, FKM, nylon and POM turned to your drawing. The fast, economical route for prototypes, urgent spares and large diameters that don't justify tooling.

✓No tooling — machined directly from rod, tube and plate stock
✓Large diameters and one-offs economically viable
✓PTFE, PU, NBR, FKM, PA6/PA66, POM — selected by medium, temperature, pressure and friction
✓Tight tolerances held on CNC lathes; every part inspected

TECHNICAL DATA

Materials & Strengths

One process, many engineering plastics — matched to the duty.

Material	Strength
PTFE	Lowest friction with broad chemical resistance — rotary and static seals
PU	Outstanding abrasion resistance for dynamic hydraulic seals
FKM	Heat and chemical duty to 200°C+
PA6 / PA66 / POM	Wear rings, guide rings and back-up rings
NBR	Economical oil-resistant seals

APPLICATIONS

Where It's Used

When you need it fast, or only need a few.

HYDR

Emergency seals for cylinders already in the field.

PROT

Prototyping

Test the design before committing to mold tooling.

BORE

Large-Bore Cylinders

Diameters where molding tooling makes no sense.

PUMP

Pumps & Valves

PTFE and PEEK-type spares for process equipment.

FOOD

Food Machinery

POM and PTFE parts for clean environments.

MNT

Industrial Maintenance

One-off replacements to keep lines running.

COMMON QUESTIONS

CNC Seal FAQ

How large a diameter can you turn?

Large bores are the sweet spot of this process — send your diameter and we will confirm.

How fast can you deliver?

Without tooling lead time, machined seals are our fastest custom route — ask for the current schedule.

How do you choose the material?

By the dominant failure risk: NBR for oil resistance at moderate temperature and low cost; FKM for high temperature or aggressive chemicals; PTFE for low friction, wide temperature and chemical resistance in rotary service; PU for high pressure, impact and severe abrasion. We also build hybrid designs — PTFE sliding elements with elastomer energizers, or back-up rings against extrusion.
