992140 Reduction Nipple | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta reduction nipple weighing 0.016 kg. It supersedes part number 42768, which was listed as a 1/8-27 to 1/8-27 nipple, and it is associated with 12 applications across the MD, TMD, AQ, TD and TAMD series through the cost records rather than the main fitment list. Note the change of description: the number it replaces was catalogued with matching ends, while this one is catalogued as a reduction nipple.

⚙️ Key Features

• 0.016 kg
• Supersedes 42768, previously listed as a 1/8-27 to 1/8-27 nipple
• Associated with 12 MD, TMD, AQ, TD and TAMD applications through the cost records
• Catalogued as a reduction nipple, unlike the matched-end number it replaces

🔌 Function

Joins two threaded connections of different sizes, adapting a line to a port it would not otherwise fit.

⚠️ Common Signs of Failure

• Weeping, misting or dripping at either end of the fitting
• Thread damaged, cross-started or corroded
• Sealing taper or cone face nicked or scored
• Fitting cracked or split at the hex

🛠️ Service Notes

• Offer both ends up to the line and the port before fitting — the number this replaces was listed with matching threads and this one is a reduction, so the two ends are worth confirming rather than assuming
• The other reduction nipple in this run, 992213, carries no published thread sizes either; order strictly on the number
