Questions and Answers for HOME-FLEX 1-1/2 in. IPS DR 11 Underground Yellow Poly Gas Pipe Coupler

A:  Hi, CrazyFrank - Pipe measurements are ID. However, since you have 1-1/4" pipe, it would be good to know the OD as well. This is because that particular size is sometimes used by municipalities and private gas companies using a thicker wall. This is shown by the "SDR" or "DR" reference on the pipe. Most frequently used is SDR-11 and the coupler you reference will work with it. Feel free to call Dave (x1026) or Jon (x1010) at (661) 257-3923 M-F 8a-5p to discuss if you'd like.

A:  Hi, Juan - No, the coupler you mention will not work with SDR-10 pipe. However, we do make an SDR-10 1-1/4" x 1-1/4" coupler. Part number 18-429-012-10. It's not a stocking item at Home Depot, but you can order them on homedepot.com (https://www.homedepot.com/s/18-429-012-10?NCNI-5) or from your store's special services or Pro Desk. We do not make any reducer couplings but you can use our 2" and 1-1/4" transition fittings with a 2" x 1-1/4" bell reducer in between them. Note that the transition fittings are SDR-11, however, and won't work with your SDR-10 1 1/4" pipe.

A:  When I bought everything for my project I made sure all my fittings and pipe were the same, in my case SDR 11. I don’t believe the homeflex makes reducer. I couldn’t find one. You can buy the underground Transition piece and maybe do it that way 

A:  Will work for 1.25 " pipe if you have the 1.25 coupler. I don't know about the reducer.

A:  Hi, John - Yes. "DR 11" is the same as "SDR 11". Thanks.

A:  No this cannot be used on galvanized pipes.

A:  It would not be advised as they are UPC approved for Poly connection only. Typically galvanized piping requires a threaded connection to meet the UPC standard.

A:  No they cannot. The internals are all plastic and would not seal properly to galvanized steel.

A:  Hi, Preferred - No, the Home Flex Underground fittings should not be used for anything other than D2513 yellow PE gas pipe.

A:  No they cannot. Only yellow plastic pipe.

A:  No it cannot it only seals to a smooth surface plus after a while the galvanized pipe will start to pit and then the gas will leak out of the pit hole where it will start to rust

A:  No, that will not cause a problem. The lip of the stiffener is not a part of the seal, so it is OK if part of it broke off. Make sure that the broken piece did not fall into the pipe. That lip stops the stiffener from going too far into the pipe. If you would like to speak to a product specialist, give us a call. (661) 257-3923. We are here from 8-5 Los Angeles Time, M-F.

A:  Hello, Thank you for your recent inquiry with The Home Depot. Search on the Home depot website using "reducer coupler 1 1/2 to 3/4" for options. We appreciate your business and look forward to serving you in the future.

A:  Good morning and thanks for your phone call recently on the same subject. As we discussed, we do not make a variable size coupler. However, one may use a combination of Home-Flex transition fittings along with an off-the-shelf reducer coupling available at Home Depot.

A:  Hi Timothy, Yes you can use our fitting on HDPE gas pipe. Be sure that the size of the fitting matches the size of the pipe. 1.25 inch DR or SDR 11.

A:  Hi, Plumbernick - Unfortunate COVID-related delays in the distribution channel have caused longer than normal lead times. However, we anticipate being back in stock in the next few days. If you haven't already done so, pull up the product on homedepot.com, put your email address in the "How to get it" area (lower right of the page) and you'll be informed when product is available to ship. Thanks. UPDATE: Part is now available on homedepot.com (4/21).

A:  Yes, each of these fittings comes with the necessary stiffeners. Tees include 3 stiffeners and couplers and elbows include two stiffeners. The stiffeners are in the package with the fitting. They are actually tucked inside the fitting, so they may not be visible when you look at the bag that the fittings are packed in. When you take the fitting out of its package, look inside the fitting and you will see the stiffeners. They are loose inside the fitting and easy to remove. Follow the fitting assembly instructions that are also in the package with the fittings. Be sure to perform your installation in accordance with you local codes.

A:  No

A:  Yes, each fitting comes with the proper number of stiffeners.
