GLI Heavy Duty 8' Double Chamber Water Tube, Black, In Ground Winter Cover Weight
Thicker vinyl for the pools that go through real winter.
The GLI heavy duty 8' Double Chamber Water Tube, Black, part 500008WTDHDBLK, is a thicker walled version of the standard water tube, built for climates where the deck ices over and stays that way, stocked under SKU PST-500008WTDHDBLK. It lays along the edge of a solid in ground winter cover and holds it against wind without the liner risk that comes from weighting a cover with blocks or bricks. The double chamber design means one puncture does not empty the whole tube. Fill each chamber about three quarters full so the ice has somewhere to expand.

What makes the heavy duty tube different?
Thicker vinyl. It resists abrasion on rough concrete and stone coping and holds up better to repeated freeze and thaw cycles, so it usually survives more seasons than a standard tube.
How full should I fill it?
About three quarters per chamber. Heavier vinyl does not change the physics, water still expands when it freezes and a tube filled to the cap will burst.
How many tubes should I order?
Enough to lay end to end all the way around the cover. Divide your pool perimeter in feet by the tube length, then add a couple of spares, since a split tube in January is hard to replace.

Let customers speak for us
The bulb was lost in transit and PST reached out proactively to ask if I wanted a replacement shipped out!
part was an exact fit for my old spa, price was great thanks
Fast shipping and great customer support. I appreciate all of the help in getting my spa up and working.
The cord worked perfectly when I upgraded my older Balboa spa and pump.
I had a leak in which water was leaking out to the waste line. I could hear the water trickling in the waste line. The spider gasket in this kit resolved the issue.
Shipping and delivery were quick. Would definitely order again from PST.
Fit perfectly and works great.
Awesome item. I can control my spa from my phone!! Love it. Item was shipoed out and delivered so fast. Hooking it up was a breeze.
The support staff to make the orders were outstanding; even though I made a quantity error. And the timeliness of all the repair parts I needed to get the OLD Tiger Shark running as good as new was wonderful. My pool is crystal clear.
Fit perfectly on our bubbler lightv
The only place I could find with the part I needed. Delivery was fast and the price was great. Best pool supply store on the web.
Part was easy to find and arrived a couple of days earlier than originally scheduled.
The ceramic spindle in the center of the original impellor broke. Replacement with this part was super easy and pump performs like new.
