Is it safe for me to DIY a new propane regulator? Image and Details included?

Some propane regulators have hoses that screw into the regulator and some have hoses that are crimped on. The hoses that are crimped on can't be removed from the regulator. If your current regulator has a hose that is threaded into the regulator, you need to find out what size thread it has. If it was designed for use in China, it very well could be a metric pipe thread. In which case you would need an adapter to get to a standard pipe thread. Then you can just screw your new regulator onto your old hose with a little Teflon tape. Your current regulator is also adjustable so you'll need to get an adjustable regulator to replace it. That would be the safest way. The easiest way would be to buy a new adjustable regulator, the proper sized barbed coupler and two hose clamps. Then just cut the old hose and the new hose. Slide a clamp on each hose, attach them with the barbed coupler and check for leaks with soapy water.

buy a new regulator [[ hose and bbq screw on ends ]] at Lowe's or the HoDepot then go to a shop that will apply your pit connector that goes to the bbq pit and accept the N. A. tank connector .... it will work that way and the new regulator is pre-set .......... do not cut the present hose or the new hose as the shop that does the crimp will discuss this with you and they will probably fix-it while you are there ... I had this done in Mexico and applied a 100lb. tank and I only had to change tanks twice a year..... you can get the 10/12lb. swap-a-tank at Lowe's or from Walmartz
