The DBH 5672 is a radial shaft seal built to hold lubricant in and keep dirt out where a shaft turns. With a 25 mm shaft, a 32 mm housing bore and a 4.00 mm height, it fits metric cavities that leave little room. The Mt configuration pairs a main sealing lip with a dust lip. Pumps, motors, gearboxes and similar equipment rely on this kind of barrier to avoid leaks and protect bearings.

Reading the code is the fastest way to confirm a match: shaft 25 mm, housing 32 mm, height 4.00 mm. Because these are standard metric dimensions, the seal drops into an existing cavity, so a worn unit can be swapped out without machining the housing. The Mt layout means the lip that seals the oil works alongside a second lip that keeps dust and grit away from the sealing edge.

Where does it earn its place? Small centrifugal pumps, low-power electric motors, speed reducers, compressors and power transmission components are common homes for this seal. In each case the job is the same: stop oil or grease from escaping and stop outside contamination from reaching the bearings. Treat it as a preventive maintenance item, since catching a worn seal early keeps shafts and bearings out of trouble.

Installation is straightforward if you prepare the shaft first. Check for burrs, nicks or a visible wear groove, and clean the sealing surface before anything goes in. Coat the lip with the same oil or grease the machine runs on, then press the seal in squarely, perpendicular to the shaft, sitting flush with the housing or slightly recessed as the design calls for. A deeply grooved shaft may call for a different size or a wear sleeve instead.

When you need a replacement or an equivalent, send part number 5672 or simply your shaft and housing dimensions and we will take it from there. We can point you to alternatives from the same brand or other compatible options.

Selection also depends on shaft speed, operating temperature and the lubricant in use, so include those details with your request and we will help you confirm the right seal for the job.
