Original BMW Sealing Compound Metering Nozzle for BMW 1–7 Series, X, Z4, and M Models (2006–2021)

Built for the bench rather than the car, the Original BMW 83-19-2-345-991 metering nozzle fits on top of a Loctite 193140 sealant bottle so the compound can be injected into a sealing injection port or along the edges of a crankshaft seal on BMW 1 through 7 Series, X, Z4, M2, M3, and M4 models from 2006–2021. BMW calls it a metering nozzle and supplies it as one piece weighing 4 grams under the BMW Group label. It is used to seal a new crankshaft seal correctly, or to seal an engine bedplate during a full engine rebuild. Each nozzle is good for one use only. BMW began producing this number in February 2013, and it is made in the United States.

Original BMW Parts carry a 24-month parts warranty.

An applicator nozzle like this meters a thin, controlled bead of compound into a tight gap, where squeezing straight from the bottle would put sealant where it does not belong. Because the nozzle is single-use, it should not be reused. Note that this is an applicator tip only; the Loctite 193140 compound is a separate purchase. It pairs with crankshaft seal replacement and with bedplate sealing on engine teardowns.
