    • Fairly easy to work with, overall happy
Size: 35 ft - 1/2''
Great product, much easier to deal with that black pipe for gas lines. Be careful cutting to length and make sure to smooth the sharp edges so you don't compromise the rubber parts. Getting the fittings back together can be a bit of a pain but once you have everything in place and threads started it comes together nicely. ... show more

Project to modify propane generator to natural gas. Buried from gas main to my generators new regulator. Fittings from Lowe's and local hardware store fit just fine. Everything went together as it should. No leaks anywhere after everything was tested

Missed my window to return bc we didn’t hook up until after 30 days ans knew it was leaking. So I am out 67 from this and another 100$ from another purchase of a reputable brand ... show more

Product is NOT 3/4 inch line. Did not discover this until installation time when 30 day return window had closed. Cost me hours of work. Amazon unhelpful on refund. Product seller and manufacturer unhelpful. Picture attached comparing ACTUAL 3/4 line the this product. If these specs are wrong, what else is faulty? Would not trust this in something as critical as a gas installation. Would not trust Amazon to hold sellers accountable. ... show more
