Bayliss power tube life is not infinite. Over the years, the piston moving through the seals gradually wears the seal material away, allowing a gradual seepage of wax out of the tube. This in turn reduces the pressure within the tube and eventually the opening distance achieved will be affected. This is when you need to replace the power tube cylinder.

Bayliss MK7 power tubes are available with 2 different models. The only difference is the operational temperatures of the power tube. The Orchid Wax model allows you to keep the greenhouse warmer in cold weather while working well in hot weather also.

Features

  • Adjustable temperature range:
    - Standard initial opening temperature range: 55° F to 70° F
    - Orchid Wax initial opening temperature range: 70° F to 85° F
  • Can be used interchangeably in the same Bayliss opener
  • Requires no electricity
  • Made in the United Kingdom

Bayliss MK7 Replacement Power Tube

I recently purchased replacement tubes for my two existing greenhouse openers. They arrived quickly and were easy to install especially with the enclosed directions, except I lost one of the 2 special washers included and had to call for a replacement. They were most responsive in quickly mailing a replacement. Suggestion: ask for 4 washers to cover any mishaps.

Perfect replacement and speedy delivery

The replacement cylinder for our greenhouse roof ventilator fits exactly. It was easy to replace using the enclosed directions, but most importantly, the product arrived very quickly.

Great service!

We bought our Growing Spaces Growing Dome in 2015 and the Bayliss automatic air vents performed effectively year-round until this past April. Our late icy Spring was followed by about five days of record-breaking heat found the vents laboring to open. We tried heating the cylinders to no avail. The replacement cylinders were in stock at ACF and arrived in time to provide the much needed automatic cross ventilation. Thanks ACF for carrying Bayliss replacement parts.
