FAQ
FAQ
Which drill models does the 86753852 diaphragm kit fit?
It's built for Montabert HC28, HC55, and HC95 rock drills. Many workshops also use it in Atlas Copco COP 2238HD+ accumulators – check your parts book to confirm the match.
What’s the diaphragm material?
A nitrile rubber compound rated for the flex cycles and nitrogen pressures you get in a hydraulic drifter accumulator.
Will this diaphragm work in my Atlas Copco COP 2238HD+?
Often yes. The diaphragm matches OEM specs for the accumulator group on those drills. Still, it's smart to verify against your serial number and parts list before ordering.
How fast can I get it?
In-stock items usually ship within a day. International express takes about 3–7 business days, depending on your location and customs clearance.
Is this a genuine Montabert part?
Yes. It’s a genuine Montabert diaphragm kit, sourced through established supply chain partners, so you get the same fit and service life as the original.
