Owners of the Rock-Flex SS Liner

I am trying to decide on which liner to get. I read a lot about the Homesaver, Ventinox, ForeverFlex being the better ones on the market ... however, the price of the Rock-Flex is attractive and they look like decent quality.

I have seen some members here recommending this SS liner ... Taken from their site:

"Wall Thickness Crush Point Weight / Foot
.006" Rock flex 338 lbs. 1.21 lbs. / 6" ID
.006" Brand A- Flex 160 lbs.
.006" Brand C 142 lbs.

It leads the industry in flexibility and strength combined. It is the very best your money can buy, guaranteed in our no hassle forever warranty."

Whoever has the flex chimney liner from Rockford Chimney Supply http://www.chimneylinerinc.com ... Can you please give us a review?

I am wondering how smooth the inside of this liner is ... since my chimney is on the short side I want my draft to be the best it could be.

Can you share your experience with this liner?


Thanks for your contribution to all of us that are trying to decide between SS Liners!

I have been reading a bunch about the different quality of SS Liners.

A few conclusions that I am coming to in my own mind are:
- the smoother the interior is the better your draft (http://www.protechinfo.com/c269/FasNSmooth-c270.html)
- the smoother the interior is the easier the cleaning
- the smoother the interior is the less creosote can get embedded into crevices
- the 316Ti is a better quality product than the others
- the welded seems are better than crimped seems (http://www.protechinfo.com/c269/Ventinox-c9.html)
- the stronger the better (https://www.savemoneywithus.com/HSUltraPro316TiAlloySSReliningPipe.html)

I really just want the best product for the cheapest price. I don't want to just go and buy the most expensive ones available just because they are expensive and have good advertising. I want to buy a liner that will serve me well for many years in all areas of typical use.

According to this: https://www.hearth.com/econtent/index.php/forums/viewthread/12601/

Forever-Flex and Rock-Flex are the same product.

I ended up emailing Rockford and this rumor seems to be false. It appears that they are not (or are no longer) the same product. See the emails below:

Hello,

I heard rumors that your 316Ti SS "Rock-Flex" liner is made by Olympia and is the exact same product as "Forever Flex".

Can you confirm or deny this rumor?

Thanks!
- Phil

Ours is as good or better, if you do not agree when it arrives please let me know, Thanks Brad

I ended up ordering from Rockford in the end because of their price, experience of forum members, and "forever" warranty.

Here are the pictures of the products that I received.

6"x25' 316Ti SS Liner for $369.99

6"x13"x13" Flat Top Plate for $39.99

6"x 45* Insert connector (adjustable) for $62

This is 3 pieces joined at the seams and is adjustable (swivels/spins) on the seams.

My total came to $472 shipped. ("free" shipping)

I am generally satisfied with the products but that is mostly because I have nothing to compare them to. Hopefully this will help others in making their big "liner decision".

Looks similar to Forever Flex. The Forever Flex came in a white box that is similar to yours, the entire liner was wrapped in plastic with the ends covered. I do like the top plate that I received from Forever Flex a little more. It is an actual cap and the sides of the plate wrap around my liner and I was able to screw it to the clay liner after applying silicone.

Seems like it sealed pretty well and I don't have to worry about water or other elements leaking in around the edges. You probably won't have that issue as long as you silicone well.

Good to hear that it looks similar to the Forever Flex.

I had the option of getting that top plate as well but I opted not to get it since I wanted to re-use my rain guard/top cap. The one you are describing may have worked but since I wasn't sure I went with the basic one. The 13"x13" top plate allows me to bend it over my 8"x12" clay liner and I will have my sheet metal friend bend for me. Then slide the old Rain Guard right over top.
