Merits M410 (M4)/ M430 (M4C) Manual Wheelchair Parts

This page lists replacement parts for the Merits M410 (M4) and M430 (M4C) manual wheelchairs. We carry 24"x1-3/8" solid and pneumatic tires and inner tubes, 12-1/2"x2-1/4" solid and pneumatic tires and inner tubes, 8"x1" caster wheels, and accessories such as wheelchair covers, bags, an oxygen tank holder and handle grips.

The two models use different rear wheels. The M410 uses 24"x1-3/8" main wheels, while the M430 uses smaller rear wheels; the tires we list for it are 12-1/2"x2-1/4". Both use 8"x1" front casters. Check the size printed on your tire sidewall before you order. The model number is on a label on the frame, often on the crossbrace. As an authorized Merits dealer, we supply genuine OEM Merits parts, with compatible alternatives on select items. Can't find your part?
