Seal types we customise

Every seal kit is built around your original — we reverse-engineer, match material, and manufacture to spec. Send us your sample; we handle the rest.

O-Rings

Radial and face-seal configurations in NBR, EPDM, FKM, PTFE, and silicone. For hydraulic, pneumatic, and static applications.

Oil Seals

Rotary shaft seals with single or double lip. Suitable for gearboxes, pumps, engines, and wheel hubs with grease or oil retention demands.

Metallic Seals

Ring joint gaskets, C-rings, E-rings, and spring-energised designs. For extreme pressure and temperature environments — flanges, valves, turbines.

CFT Seals

Carbon, Fibre & PTFE composite seals for chemically aggressive media. Excellent wear resistance for rotating and reciprocating surfaces.

Nylon Seals

Polyamide-based seals for low-friction, high-load environments. Common in hydraulic cylinders, rod guides, and light industrial machinery.

Custom Seals

Unique profiles, multi-material assemblies, or hard-to-source replacements. If you can send us the original, we can match or improve it.

Materials, ratings & applications

Choosing the wrong material leads to premature failure. Here’s a complete reference for every material we work with and where it belongs.

From your original to production kit

Send us your original seal or worn component. We develop, match, and return everything — original included.

01 — SUBMIT
Send us the original
Ship or hand-deliver your original seal, gasket, or worn component. We need it for dimensional measurement and material identification.
02 — ANALYSE
We measure & material-match
Our team measures cross-section, inner/outer diameter, and hardness (Shore A/D). Material type is confirmed via surface analysis or datasheet matching.
03 — DEVELOP
Production begins
Seals are manufactured in the matched or upgraded material. Standard orders: 1 day. Complex or high-quantity kits: up to 1 week.
04 — DELIVER
Kit + original returned
Your complete seal kit is packaged and dispatched. Your original sample is always returned alongside — no exceptions.

Built around your needs

We’re not a catalogue supplier. Every kit is developed fresh from your original, with full traceability.

Fast lead times

Simple kits in as little as 1 day. Even high-complexity or bulk orders ship within 1 week. No weeks-long catalogue delays.

Original returned, guaranteed

We only borrow your original to reverse-engineer. It is always returned with your finished kit — no exceptions.

Any seal, any profile

Non-standard shapes, multi-lip designs, obsolete replacements — if we can measure it, we can make it.

Material traceability

Each kit comes with material grade confirmation. Critical for food, pharma, and oil & gas compliance requirements.
