SPEEDAIRE Seal Kit CQS Series 20
This SPEEDAIRE seal kit belongs to the CQS series and is built for the size 20 compact cylinder. It provides the piston seal, rod seal and tube gasket needed to restore pneumatic sealing performance. Maintenance technicians working with SMC CQS cylinders use this kit for scheduled rebuilds or leak repairs. The components are supplied new and ready for installation.
Verify CQS series and size 20 compatibility
Before ordering, confirm that the target cylinder carries the CQS series designation and the size 20 marking. Cross-reference the cylinder part number with SMC documentation to ensure the piston seal, rod seal and tube gasket match the bore and rod dimensions. Using this kit on a different series or bore size will result in improper fit and continued leakage.
Suits SMC CQS compact cylinder maintenance
This kit suits technicians servicing SMC CQS series compact cylinders of size 20 who need a complete seal set for a single rebuild. It is not for buyers who want individual seals sold separately, those working on larger bore cylinders, or anyone repairing cylinders from a different series or brand. The package contains only the three seals listed for this specific model.
