Seal kits and repair kits are available for all standard single-acting gas return cylinders. Seal kits include all normal wear items such as O-rings, seals, and nylon tip set screws. Repair kits include everything in the seal kit with the addition of wear bands and select components that may require occasional replacement.
These kits are for single-acting gas return cylinders made from 2014 to the present. If the cylinder was made before 2014, please contact Harken with date purchased and serial number to confirm the seal or repair kit needed.
Service and repairs should be made by a certified hydraulic technician.
