is a German Institute for Standardization (Deutsches Institut für Normung) standard titled "Radial shaft seals with casing" . It specifies the dimensions, material requirements, marking, and performance characteristics of radial shaft sealing rings (commonly known as oil seals or rotary shaft seals) with a metallic or elastomeric casing.

DIN 3760 is intended for or low‑pressure applications only. Exceeding the maximum allowable pressure will cause the sealing lip to lift off the shaft, resulting in immediate leakage. For pressurized systems, specially reinforced seals (e.g., Type AS-P or AS-PX) or mechanical seals must be used. din 3760 pdf

This type features a fully rubber-covered outer diameter. It provides excellent static sealing in the housing bore, even if the housing expands thermally or has a rougher surface finish. Type AS (Form AS) Exceeding the maximum allowable pressure will cause the
