Can Type L copper tubing be used for LP gas?

In 1999, the International Association of Plumbing & Mechanical Officials (IAPMO) designated that copper tubing and fittings are allowable for gas-distribution systems, including propane.

What can Type L copper be used for?

Type L Copper Pipe: Type L copper pipe is used for interior plumbing, fire protection, and some HVAC applications. It is available in rigid and flexible forms and can be used with sweat, compression, and flare fittings. Type L copper is thinner than Type K but thicker than type M.

Can copper fittings be used for gas?

Steel, copper, brass: The most common gas piping is black steel. Galvanized steel, copper, brass or CSST (Corrugated Stainless Steel Tubing) also can be used in some areas, but some utilities specifically prohibit the use of copper.

Should I use L or M copper?

Type L copper pipe is recommended where you need strength and protection. But for normal “in the wall” household plumbing, Type M copper pipe is just fine. The beefier Type L is often used underground, in hot water heating systems, for commercial plumbing and for gas line (where permitted).

What is the difference between Type K and Type L copper tubing?

Type K is the heaviest. Type L is medium weight and used most often for water lines in homes. Type M is thinner and is used underground or for light domestic water lines if local codes allow.

What type of copper tubing should be used for propane?

Soft Copper Tubing Coils, Type L, for use with propane.

What type of copper is used for compressed air?

Copper pipe is a common selection for sensitive compressed air systems and when correctly sized and connected is very durable and effective. Type M hard, type L hard and type K soft copper has a working pressure of 250 psig (17 bar). Type K hard copper is rated for 400 psig (27 bar).

Can you bury Type L copper?

Type L Copper Pipe Type L is beefy enough to be used in underground applications but is often used to replace or repair water lines. It comes in both flexible rolls and rigid tubing, with the rigid tubing usually used for internal water piping and the flexible rolls used underground and outside the home.

What type of copper is used for gas?

The types of copper tube that can be used in fuel gas distribution systems are Types K and L, up to and including one-inch outside diameter. Both type L and K are used for underground lines.

What is the difference between L and M copper tubing?

The key difference between types L and M is their pressure rating and wall thickness. The most common copper pipe sizes are ½ and ¾ inches. Type M ½ inch measures 0.028” in wall thickness whereas type L ½ inch measures 0.04” in wall thickness.

Can you use Type L copper refrigeration?

Type L copper pipes are typically used for residential water systems. Copper, used for refrigeration, is designated as ACR copper. Measure the inside and outside diameter of the end of the tube. The outside diameter of Type L is always 1/8-inch larger than the size marked on the tube.

Do you need Type L copper pipe for well water?

But check with your building inspector; some areas require Type L. Acidic water with a pH of 7 or less can be hard on copper pipe. If you have a well and find out from testing that the water is acidic, you may want to use the thicker-wall Type L pipe; better yet, use “plastic” CPVC pipe and fittings.

What is the difference between Type K and Type L copper pipe?

Type L is known as the most common form of copper piping because it can be used in far more applications than Form K. Flexible Type L Piping may be used for repairing or modifying old water pipes but the rigid tubing is more robust. Form L can also be used outside the house, where it would directly be displayed.

Can copper pipe be used for propane?

For propane, you can use Type L copper with plastic sheath to protect from contact with lime in cement. Type L can also be direct buried or penetrate through walls, ceilings and floors. No refridgeration tubing can be buried, but it can be used for LP supply where accessible only.
