Key Features
Overview
The Mirka O-Ring MPA0042 is a replacement O-ring for Mirka pneumatic sanders. This is an O-ring designed for maintaining or repairing the sealing function in compatible air sanders. Model Number: MPA0042. If you are servicing a Mirka air sander and need the correct replacement part instead of a generic ring that may or may not fit, this is the part you want to start with.
Small parts like this matter more than most people think. On a pneumatic sander, the seal has a direct effect on how the tool operates and holds up over time. When an O-ring wears out, hardens, or gets damaged during service, the fix is usually straightforward, but only if you have the right replacement on hand. Using the Mirka O-Ring MPA0042 keeps the repair focused on restoring the tool rather than guessing at fit.
Because this part is listed specifically for Mirka pneumatic sanders, it makes sense for technicians, body shop users, woodworking pros, and serious shop owners who prefer OEM service parts over trial-and-error substitutes. That is especially important on air tools, where consistent sealing and correct sizing help prevent downtime and repeat tear-downs.
This is also the kind of part that is worth keeping in stock if you service your own tools. It is inexpensive, compact, and easy to store, but it can save you real time when a sander is already apart on the bench. For repair work, the right small part is usually cheaper than lost labor.
The listed size is 15 mm, which gives buyers an important reference point when matching service parts to the intended tool. Mirka also identifies this part clearly as MPA0042, making it easier to confirm you are ordering the exact replacement instead of relying only on a visual match.
If you run Mirka air sanders and want the correct replacement sealing part for maintenance or repair, the Mirka O-Ring MPA0042 is a practical buy. It is best suited for users who already know the part number they need, shop owners maintaining multiple sanders, and anyone trying to keep a pneumatic sanding setup working without unnecessary downtime.
Keep Your Sander in Service
A worn seal can turn a simple service job into tool downtime. Replacing it with the correct Mirka O-Ring MPA0042 helps keep a compatible pneumatic sander ready for sanding work instead of sitting on the bench waiting for parts.
