JF015E CVT Sealing Ring Kit

The JF015E CVT Sealing Ring Kit is an internal sealing-ring set used during repair and rebuilding of the Jatco JF015E continuously variable transmission, also known as Nissan RE0F11A. The product shown contains four sealing rings in two different sizes and colors, commonly supplied as an oil-ring repair set for internal shaft, sprocket or pulley-related sealing applications.

Professional transmission catalogs list dedicated sealing-ring kits for JF015E / RE0F11A transmissions, confirming that these rings are normally replaced as service components during internal CVT rebuilding. Alltranz, for example, lists a JF015E sealing ring kit under industry reference C17250K, while other specialist suppliers market a JF015E sprocket wheel oil ring kit under reference 181611B.

This product is intended for professional CVT workshops, transmission rebuilders, distributors and wholesalers. Because several sealing-ring positions exist inside the JF015E transmission, the original ring dimensions and installation location should be confirmed before ordering.

JF015E CVT Sealing Ring Kit Function

The JF015E CVT Sealing Ring Kit helps maintain hydraulic pressure and control transmission-fluid leakage between rotating or stationary internal components. These rings operate in precision-machined grooves and form a hydraulic seal while allowing related shafts or assemblies to rotate.

Correct sealing is important in a CVT because hydraulic pressure is used throughout the transmission for pulley control, clutch operation and lubrication.

If a sealing ring becomes worn, hardened, cracked or damaged, transmission fluid may leak internally past the sealing surface. Internal leakage can reduce hydraulic efficiency and may contribute to pressure loss or poor transmission operation.

Go4Trans specifically notes that worn sealing rings are an important JF015E repair item and that Teflon rings are often replaced during input-shaft, friction, bearing and belt-related repairs.

Four-Piece Oil Ring Configuration

The product shown in your photo contains four rings:

• Two larger dark-colored sealing rings
• Two smaller light-colored sealing rings

This configuration should be described according to the actual product rather than simply calling it a universal complete sealing-ring kit for the whole transmission.

JF015E professional catalogs list multiple individual sealing-ring locations, including input-shaft, end-case-to-pulley, input-pulley, output-pulley and output-shaft sealing positions.

For this reason, a four-piece product may represent a specific pulley, sprocket or gear-area repair set rather than every sealing ring used throughout the JF015E transmission.

181611B Industry Reference

A current transmission supplier lists 181611B as an OE/reference number for a JF015E / RE0F11A sprocket wheel oil ring kit. The same listing describes it as a repair product for the JF015E CVT.

However, this number comes from aftermarket transmission-parts supply data rather than a Nissan factory EPC source.

Therefore, for your website I recommend:

Industry Reference: 181611B

rather than:

Nissan OE: 181611B

If your packaging or supplier label specifically shows 181611B, you can safely include it in the product title or product-reference field.

JF015E and RE0F11A Application

JF015E is the Jatco transmission designation, while RE0F11A is the corresponding Nissan designation. This compact CVT is used in various Nissan, Suzuki and Mitsubishi applications depending on vehicle model and market.

The transmission combines a CVT pulley system with additional internal gearing, making correct hydraulic sealing especially important.

Customers should identify the transmission by code rather than relying only on the vehicle model. Clear photos of the original rings, ring dimensions and installation location can help confirm the correct kit.

Professional CVT Rebuilding

During JF015E rebuilding, technicians should inspect the sealing-ring grooves and mating surfaces before installing replacement rings.

A new JF015E CVT Sealing Ring Kit should not be installed onto damaged, scored or excessively worn surfaces. Technicians should also inspect nearby shafts, pulley components, bearings and hydraulic passages.

Sealing rings should be installed carefully to avoid stretching, twisting or damaging the sealing edge. Some polymer or Teflon-style transmission rings may require sizing or controlled installation procedures depending on their design.

Clean CVT fluid and professional assembly procedures should be used during rebuilding.
