01
Oil Seals
Rotary shaft seals for engines, transmissions, hydraulic equipment. Standard automotive sizes (used on Hino, Suzuki, Honda since 2003) and custom dimensions on in-house CNC tooling.
NBR · FKM · HNBR · service to 130–200 °C.
PBR — Rubber Components: Seals, Hoses, and Custom Molded Parts
Oil seals, water pump seals, drum seals, duct hoses, and custom molded rubber components on the same near-fully integrated factory floor that supplies Hino, Suzuki, Honda, and ROKI.
The Rubber Components range covers the unbonded, all-rubber side of our product mix: oil seals, water pump seals, drum seals, custom molded parts, and air-intake duct hoses produced on vertical injection presses. These are the parts where the compound itself does the work — material properties have to match the operating environment exactly, and the production discipline has to hold those properties consistent across every batch.
Sub-categories
What This Range Includes
02
Water Pump Seals
Coolant-line sealing for automotive and industrial water pumps. Compounds chosen for coolant contact and thermal cycling.
EPDM for coolant · NBR for hybrid coolant-oil.
03
Drum Seals
Sealing rings for steel and plastic drums carrying oil, chemicals, water, or food-grade contents. Compound matched to fluid.
NBR / EPDM / FKM / silicone (VMQ).
04
Custom Molded Parts
When the seal, gasket, or rubber component you need isn't in any catalog, we tool and produce it. Drawing, sample, or concept — we measure on the QC microscope, cut the tool in-house.
All compounds · Shore A 30–90 · prototypes to series.
05
Air-Intake Duct Hoses
Moulded EPDM and silicone intake hoses produced on vertical injection presses. Standard automotive sizes and custom diameters.
EPDM · silicone (VMQ) for high temperature.
06
Industrial Sealing & Gaskets
Custom gaskets and rubber sealing parts for industrial machinery, conveyors, compressors, and production equipment.
NBR / EPDM / FKM / silicone · Shore A 40–80.
Process
How a Rubber Component Goes From Compound to Carton
01
Weighing
Automatic chemical weighing — recipe traceability from the first kilogram.
02
Kneading
55-litre or 75-litre internal mixer develops compound properties.
03
Mill + test
Two-roll mill finishing and rheometer cure-curve check.
04
Mold
Vertical injection or compression molding — matched to part geometry.
05
Finish & QC
Post-cure for silicone/FKM, deflashing, inspection, packaging.
