Vibrant Crush Washers M22 (10 Pack)

Aluminum Crush Washers for M22 Straight-Thread Metric Adapter Fittings

The Vibrant 20948 is a 10-pack of M22 aluminum crush washers designed for use with straight-thread metric adapter fittings that seal against a machined port face rather than using an O-ring groove. Straight-thread fittings used in oil pans, valve covers, remote filter housings, and transmission cases often require a deformable sealing washer to create a leak-proof interface between the fitting flange and the port.

Rubber or copper washers are common in OEM applications, but Vibrant's aluminum crush washers provide a clean, repeatable seal that is compatible with all Vibrant metric adapter fittings. When the fitting is torqued, the aluminum washer plastically deforms slightly, conforming to any minor surface irregularities in the port face to create a positive fluid seal. The M22 size accommodates the thread size found on many common Vibrant metric adapter fittings for AN-to-metric oil port connections.

Each 20948 kit contains 10 washers, providing enough units for multiple service intervals or multiple fittings on a single build.

Frequently Asked Questions

What Vibrant fittings use the M22 crush washer?

The 20948 M22 crush washers are used with Vibrant Performance M22 straight-thread metric adapter fittings. These are typically AN-to-metric adapters used to connect AN braided or PTFE lines to metric-threaded ports on oil pans, valve covers, remote oil filter housings, and transmission fluid taps. Check the thread size of your specific Vibrant adapter fitting before ordering to confirm the M22 size is correct for your application.

Are aluminum crush washers reusable?

No. Crush washers are single-use components. When the fitting is torqued, the washer plastically deforms to create its seal, and that deformation cannot be reversed. Each time a fitting is removed and reinstalled, a new crush washer should be used to ensure a proper seal. The 20948 kit includes 10 washers to provide spares for future service intervals.

Can the 20948 washers be used with non-Vibrant metric fittings?

The 20948 is primarily sized and specified for use with Vibrant Performance metric adapter fittings. However, as a standard M22 aluminum crush washer, it may also function correctly with other brands of M22 straight-thread fittings provided the outer diameter and thickness are compatible with the port face and fitting flange geometry. Confirm fitment with your specific fitting manufacturer if using with non-Vibrant fittings.

What is the difference between a crush washer and a copper banjo washer?

A crush washer is used with straight-thread fittings that thread directly into a port, where the washer sits between the fitting flange and the port face. A copper banjo washer is used with hollow banjo bolt fittings that have a fluid passage through the bolt center, with a copper washer on each side of the banjo eye. These are two different sealing methods for different fitting styles. The Vibrant 20948 is a crush washer for straight-thread metric adapters, not a banjo washer.

What fluid types are these aluminum crush washers compatible with?

Aluminum crush washers are compatible with most automotive fluids including engine oil, automatic transmission fluid, gear oil, coolant, and gasoline-based fuels. They are not suitable for use with brake fluid, which requires specifically rated sealing hardware, or in pressurized high-temperature steam applications. For fuel system use, confirm that the fitting and port material combination is appropriate for your specific fuel type.

Do I need a torque wrench when installing with these crush washers?

Using a torque wrench is strongly recommended. Over-torquing an aluminum crush washer can cause it to shear, strip the port threads, or crack a soft-material port boss. Under-torquing will not produce sufficient deformation for a leak-free seal. Follow the torque specification provided by Vibrant Performance or the adapter fitting manufacturer for M22 metric straight-thread fittings, typically in the range of 25 to 40 Nm depending on the port material and fitting design.

How do I know which Vibrant crush washer size I need for my adapter fitting?

The crush washer size corresponds to the thread size of the metric adapter fitting. A Vibrant M22 adapter fitting requires the 20948 M22 crush washer. For other sizes, Vibrant offers crush washers in M6 through M24. Reference the part number on your Vibrant adapter fitting box or the Vibrant catalog to identify the thread size, then select the matching crush washer pack.

What warranty does Vibrant provide on the 20948 crush washers?

Vibrant Performance provides a manufacturer warranty on their components covering defects in materials and workmanship. Under the Magnuson-Moss Warranty Act, using aftermarket hardware components in vehicle plumbing does not void the manufacturer warranty on unrelated vehicle systems. Contact Vibrant Performance for specific warranty terms for consumable hardware items.
