The company now offers fuel systems, electrical components, battery charging solutions, and NMEA electronics alongside their traditional engine parts lineup.</p><h3>Quality Backed by Industry-Leading Warranties</h3><p>What sets Sierra apart in the crowded aftermarket marine parts market is their commitment to standing behind every component they manufacture.

Product Details

The Sierra 18-32882 is a replacement water tube seal (also referred to as a water supply tube grommet/seal) designed for Volvo Penta and OMC sterndrive applications. This seal is responsible for sealing the water inlet tube into the upper unit of the sterndrive, preventing water intrusion and ensuring proper cooling system integrity.

Sierra International is the aftermarket marine industry's leading supplier of replacement parts, offering direct OEM cross-reference coverage across all major engine brands. The 18-32882 directly replaces Volvo Penta/OMC OEM part number 3852315.

Key Features:

  • Direct replacement water tube seal for Volvo Penta and OMC sterndrive upper units
  • Replaces OEM part number: 3852315
  • Sold individually (priced per piece)
  • Also found as a component within Sierra lower unit sterndrive seal kits
  • Manufactured to Sierra's high-quality aftermarket standards

This seal is a common wear item serviced during lower unit gearcase seal kit replacements on Volvo Penta AQ-series and SX-series sterndrives, as well as OMC Cobra SX sterndrive units. Inspect and replace this seal any time the sterndrive is disassembled for service to ensure a proper watertight seal.

shopping was easy

Excellent service

Love no tax and free shipping!

Great company to deal with. I placed an order with them (albeit an incorrect shipping address) and before you know it I'm expecting delivery in a very short amount of time. I also did have to call and attempt to correct my address error when the customer service rep let me know that all is well and set to be delivered to the correct address. I appreciate the fact that the gentleman on the other end of the phone was reassuring, courteous, and professional. I'd certainly do business with them again as the prices and customer service can't be beat!

Best price on the Internet! Fast Shipping and great communication. I will definitely do business with them again!
