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 Bayliss MK7 power tube works great. I ordered two for my greenhouse. They are very easy to install. If you ordered these then you must order the Replacement Spacer Set. Shipping was fast too!

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.

The vent power tubes were overdue for replacement. The new ones are easy to install. Highly impressive was the very rapid shipping from the east coast to California, even the second time I ordered, after discovering I had ordered one too few.

If you depend on a Bayliss opener for cooling, ALWAYS have a spare power tube on hand. They all wear out eventually. Don't try to change it without removing the opener from the greenhouse. Been there, done that.

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.
