Lip seals held to DIN/ISO — batch after batch.
NBR and FKM compounds, stocked standard sizes and tooled non-standards — for construction and agricultural machinery that cannot afford a failed seal mid-season.
DIN 3760 / ISO 6194 housing fits.
Bore, OD, and lip-spring geometry conform to DIN 3760 and ISO 6194. Every production run is gauge-checked before shipment — no batch-to-batch drift.
Standard bore range: 15 mm – 400 mm OD. Non-standard tooling quoted within 3 business days; lead time confirmed before production begins.
Material follows temperature and fluid — not preference.
NBR — General duty
FKM — High-heat duty
Operating range −20 °C to +100 °C. Resistant to mineral oils, hydraulic fluid, and fuel. Correct compound for most construction and agricultural gearbox applications.
Operating range −20 °C to +200 °C. Compatible with synthetic fluids, aggressive chemicals, and high-temperature engine environments where NBR degrades prematurely.
Know your bore and fluid. We confirm the rest.
Send your bore size, operating temperature, and fluid type. We return a compound recommendation, stocked availability, and lead time — no renegotiation later.
