9996666 Nipple | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta 9996666, weighing 0.082 kg. Volvo Penta's own special tools catalogue designates it a nipple rather than a connector, and lists it for the D3 range and the D11 and D13 engines, 106 product designations in all. It supersedes 9995270, which the same catalogue shows as a pressure gauge listed for the D3 range, and 9995270 is superseded by nipple 9996591 and by 9996398 as well, so that one old number is now covered by three current tools. 9996591 sits two grams away at 0.084 kg but is listed against the D9 and D11 engines instead, which is the difference the scale cannot show.

⚙️ Key Features

• Designated a nipple in Volvo Penta's special tools catalogue
• 0.082 kg
• Listed for the D3 range and the D11 and D13 engines, 106 designations
• Two grams from nipple 9996591, which is listed for the D9 and D11 engines instead

🔌 Function

Forms the threaded joint between the test gauge and the point being measured, so the pressure reaches the instrument without leaking.

⚠️ Common Signs of Failure

• Thread damaged, crossed or stripped at either end
• Sealing face or seat nicked, so the joint weeps under pressure
• Body cracked or distorted from over-tightening
• Hex flats rounded off

🛠️ Service Notes

• 9996666 and 9996591 sit two grams apart, so use the product lists or the tool number rather than picking by eye
• The old 9995270 maps onto this nipple, nipple 9996591 and 9996398, so check which of the three your test set-up needs
• Depressurise the circuit before making or breaking the connection
