The DBH 1373Tef oil seal is a lip-type radial seal, designed to retain lubricant and stop the ingress of dust, water or particles at the point where a shaft passes through a housing. It is mounted in gearboxes, pumps, electric motors and transmission equipment, and works supported on the rotating shaft with the lip in contact. It is a wear part: when oil loss or dirt ingress appears, it is replaced and the equipment seals again.

This item is identified with the designation 1373Tef and corresponds to a radial shaft seal from the DBH line. According to the product page data, the shaft diameter is 88 mm, with design A 435-R AH. For the housing diameter and height, the manufacturer's product page lists values that must be confirmed before ordering, because they appear as 0 and 000. Do not take those figures as actual dimensions: they are verified against the DBH catalog at the time of inquiry.

Typical applications for a seal of this type are in equipment with a rotating shaft and internal lubrication: gearboxes, reducers, centrifugal pumps, motors, rollers and continuous-process machines. In all those cases the seal performs two functions at once, retaining oil inward and blocking dust or water outward. That is why it is advisable to inspect it every time the assembly is disassembled and replace it if the lip is hardened, cut or visibly leaking.

To install a radial shaft seal, work with a clean shaft free of burrs, lubricate the lip with the same grease or oil as the equipment and press the part in perpendicular to the shaft. If the housing has a shoulder, use an installation sleeve or a flat-faced tube so as not to deform the lip. In the selection, in addition to the shaft diameter, the design type, lip material and rotation speed matter; those data are cross-checked with the manufacturer's product page before confirming the replacement.

If you need an equivalent, send us code 1373Tef along with the shaft diameter and, if possible, a photo of the old part or the housing. With that we search the DBH line and compatible alternatives, and confirm which option fits without modifying the assembly. We can also check whether design A 435-R AH has a direct replacement within the same oil seal category.
