9990124 Nipple | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta nipple 9990124, a threaded connection fitting for workshop test equipment, weighing 0.134 kg. Volvo Penta's own special tools catalogue lists 59 products against it, all of them TAD industrial engines plus the D11 4f JP and D13 4f JP, and prints nothing at all against its near twin 9990125 at 0.129 kg. Five grams separate the pair on the scale, so the product list is the only thing that actually tells them apart.

⚙️ Key Features

• Test-equipment connection nipple
• 0.134 kg
• Listed for 59 products, all TAD engines plus the D11 4f JP and D13 4f JP
• Near-identical to nipple 9990125, which carries no product list

🔌 Function

Forms the threaded joint between a test hose or gauge and the port being measured, sealing it against pressure.

⚠️ Common Signs of Failure

• Thread stripped, crossed or picking up on assembly
• Weeping or blowing at the joint once pressure is applied
• Sealing face nicked, scored or coned over
• Hex flats rounded off by over-tightening
• Bore blocked with old sealant or debris

🛠️ Service Notes

• The published weights do not separate 9990124 from 9990125, so order by number and check the thread against the port before fitting
• Renew rather than re-cut a damaged sealing face, since a marked face will not seal reliably at test pressure

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
