Large Flexible Cylinder Comfort Sleeve
(10 customer reviews)

£39.99

This Large Flexible Cylinder Sleeve has all the advantages of our smaller seal but is designed for cylinders with an opening of 3 1/2″ and 4″ diameters.  These seals are NOT compatible with the deluxe flanged cylinders. If you want to use the seal with one of our Two Stage Cylinders, we can modify the Two Stage at manufacture. Please let us know when you order.

This item is effectively a moving part and needs special care. Important instructions  are included with each seal, but you can view them here prior to purchase.

PLEASE NOTE:  These items are imported and with the current exchange rates, we make no profit on them after tax, shipping and import costs. The price is  entirely the cost to us and these are offered as a service to our customers.

    Great seal. It is soft and fit also the Monstertube 😉 the mountig with MT is fiddly. You should use an electric pump.

    One of a kind on the market – this sleeve is awesome and gives the best comfort.

    I ordered a new sleeve as a replacement for the original sleeve that came with the Long Jonny cylinder which I purchased in April 2018. I didn’t realise that my old sleeve became stiff, however in the end I experienced some difficulties keeping a good seal. I am also not sure if the sleeves are the same, the new one is whitish whereas the old one is yellow. With the old sleeve I pumped roughly 500 hours which I think is a really good lifetime. The old sleeve used to creep into the cylinder and when it became stiff it is inclined to more and more keep this shape. Therefore I decided to push on the cylinder when increasing vacuum so that the sleeve stays in place. Another method is to pull gently on the sleeve when the cylinder is under vacuum so that it moves back to the relaxed position. Other than that I am following the recommendations from Thickwall Cylinders.

    I highly recommend this sleeve.
