The QA1 valve disc kit includes eight 1.300 in OD, 0.012 in thick valve discs, packaged as an 8-pack for service and rebuild use. These larger-diameter, consistent-thickness discs serve as direct replacements for valve assemblies where this specific dimension is required. Supplying matched pieces in a single kit simplifies maintenance and helps maintain predictable hydraulic behaviour during reassembly.
