Hi, I have a corbin series 100 hydraulic door closer that leaks oil from the arm spindle, can I use this o-rings to reseal it?

Hello. If that device uses ORS/ORFS hydraulic fittings, then this would work for it. You may be able to look in the product's manual for information on the o-rings. Feel free to contact Captain O-Ring directly if you're able to find a part number or specs in the manual. We'd be happy to help with it.

Is the width of these O-rings 0.07 inches?

Hello. Yes, that is the standard cross section (width) for ORS/ORFS o-rings. :-)
