Marine Gaskets, Seals & O-Rings

Engine Gaskets, O-Rings, Oil Seals, Water Seals, Bellows, Washers & Sealing Kits

Shop marine gaskets, seals, O-rings, sealing washers, bellows, and service kits for engines, drives, cooling systems, fuel systems, exhaust, pumps, filters, housings, and routine maintenance repairs.

Shop Gaskets & Seals Engine Gaskets O-Rings
Fitment Check

Match sealing parts by engine brand, serial number, drive model, part number, service location, material, size, and the fluid or pressure being sealed.

Ask Parts Desk

Gaskets and seals can look simple, but the wrong thickness, profile, material, or diameter can cause leaks, overheating, water intrusion, or repeat service work.

Find Sealing Parts Faster

Search by Part Number, Engine, Drive, Size, or Service Area

Use the search box for exact part numbers, engine serial numbers, drive models, gasket sets, O-rings, oil seals, water pump gaskets, exhaust gaskets, fuel seals, and seal kits.

Engine Sealing

Gaskets for Maintenance, Repairs, and Reassembly

Engine sealing parts include valve cover gaskets, head gaskets, intake gaskets, oil pan gaskets, timing cover seals, thermostat gaskets, pump gaskets, sealing washers, and O-rings.

Oil Pan GasketsIntake GasketsRocker Cover Gaskets

Water, Oil & Drive Sealing

Seals That Keep Fluids Where They Belong

Oil seals, water seals, shaft seals, drive seals, bellows, drain plug washers, pump cover gaskets, and O-rings help keep oil in, water out, and systems protected.

Shaft SealsWater Pump GasketsPlug Washers
LOC

Match the Exact Location

A seal for a pump, drive, cooler, injector, filter, or drain plug may have a similar name but a different size, material, or profile.

SER

Use Serial Numbers

Sealing parts can change across engine families and production ranges. Serial number and part number are the best starting points.

KIT

Check Related Parts

Some repairs need several sealing parts at once: gaskets, O-rings, washers, clamps, bellows, hardware, sealant, or service kits.

Fitment Guidance

Small Sealing Parts Can Decide the Whole Repair

A wrong gasket or seal can lead to leaks, overheating, fuel smell, oil contamination, water intrusion, exhaust leaks, or repeat labor. Search by the original part number when possible, or send the Parts Desk the engine and service details.

Ask Parts DeskGasket KitsSealing Rings
Have the old part handyPhotos of the gasket, seal, O-ring, package label, or service location can help confirm the correct replacement.
Search clearlyTry part number first, then engine brand plus the exact item: exhaust gasket, shaft seal, impeller O-ring, or drain washer.
Confirm material and sizeO-rings and seals may differ by fluid type, diameter, thickness, shape, temperature range, and pressure.
Inspect the surfaceClean sealing surfaces, damaged housings, corrosion, worn shafts, and improper sealant can cause repeat leaks.

Gaskets, Seals & O-Rings FAQ

Choosing the Right Sealing Parts

Should I search by part number or by the part name?

Search by part number first whenever possible. If you do not have it, search by engine brand, serial number, and the exact sealing location.

Are O-rings, gaskets, and seals interchangeable?

No. O-rings, flat gaskets, sealing washers, and oil seals are designed for different surfaces, fluids, pressures, and movement. Match the original style and fitment.

Should I replace related sealing parts during service?

Often, yes. Many jobs also need O-rings, washers, bellows, clamps, hardware, or a service kit so the repair can be completed cleanly.

Can the Parts Desk help identify a gasket or seal?

Yes. Send the engine or drive serial number, old part number if available, photos, measurements, and where the part installs.
