Bayliss Mk. 7 replacement power tube spare cylinder Greenhouse Vent Opener Spare

Description

BAYLISS Mk. 7 replacement powertube
Spare cylinder to renovate non working Bayliss Mk. 7 Autovents
After several seasons dust and general dirt can wear the seals around the piston and allow the mineral wax to weep out. Eventually the unit will stop working correctly and the only solution is to replace the cylinder unit, (power tube).
Please note that these cylinders will only fit the Bayliss Mk. 7, Mk.7 Triple Spring and Mk.7 Hydraulicheck models - we also stock the Mk.7 Super cylinders available from a seperate listing in our eBay store
Bayliss XL powertubes, Thermofor actuators and Orbesen spares are also available in our Autovents section of our ebay shop.
Brand new stock available for immediate despatch.
We also stock the full new units - Bayliss XL, Bayliss Mk. 7 and several autovent models from Thermofor - a standard model and a heavy duty double spring model for use in exposed locations. We also supply the side louvre vent openers as well as spare cylinders for all the Thermofor models.
