I have read different concerns about pex piping being dangerous to transfer LP gas. I have an application that I was going to run LP gas underground to a black pipe riser outside of a garage. From the black pipe it would go to a regulator on a LP Gas rubber Mr. Heater hose to a ventless heater inside. It was hitched up to a 100lb cylinder before. From what I read, this will not work. Why is that? Thanks.

Why is PEX-AL-PEX an excellent piping material for plumbing and gases?
PEX-AL-PEX is ideally suited for potable water and fuel gases applications. It is flexible, making it easy to install and service. PEX-AL-PEX is able to withstand the high and low temperatures found in plumbing and heating applications, and is highly resistant to chemicals found in the industry environment.
Flexible systems are quieter than rigid piping. The smooth interior will not corrode which can affect other materials long term pipe flow characteristics. PEX-AL-PEX is also very freeze- break resistant. PEX-AL-PEX systems have fewer joints and are easier to install providing a lower cost installation over traditional steel and copper materials.
How can I be sure that PEX-AL-PEX is a safe product for gas use?
PEX-AL-PEX is manufactured and tested according to stringent national consensus standards: ASTM F 876, F 877, AWWA C904 and CSA B137.5 and as4176.Both the product manufacturer and independent third party testing agencies conduct routine quality control and quality assurance evaluations to insure the product meets ASTM, ANSI/NSF International and CSA Standards. Compliance with the standards ensures the end user of safety and quality. Additionally, PEX-AL-PEX is included in all of the major model plumbing codes used in the United States , Australia and Canada; NPC, UPC, IPC and NSPC, and approved by HUD for hot and cold potable water plumbing and gas use.
