I use the "gas" rated Teflon tape. It is thicker and easier to deal
with,
and it is identified by it's yellow color.

Ok, that's enough information for me. I've used Teflon tape on plumbing
joints before, so I'll pick up some of the yellow version. Just for
interest's sake, I bought the Dewalt D55141 compressor you told me about.
Haven't run it yet because I was waiting for an order of hose and fittings
to come in which just did. I'll pick up the tape this weekend and let you
know how loud this 85db compressor sounds compared to the old one that I'm
giving to a friend.

Do you know if the yellow version tape will do double duty on regular
plumbing fixtures? ~ not a money thing, just a convenience if it will
work.


Yes, it works on regular plumbing, it is thicker and takes less.


Found this on-line:

TEFLON TAPE:

When PTFE (Teflon) tape first became available they only made it in the
common single density type, which we commonly find in the hardware and home
supply stores. Later they began making a double density version, which was twice
as thick. Many state and local codes then adopted the double density type as
mandatory when making connections for natural gas however since both products
were the same color (white) it was difficult for inspectors to be sure which
product had been used. PTFE tape is now made in numerous varieties and they have
issued a color standard to determine which type should be used.

WHITE-Single density- should only be used on NPT threads up to 3/8 inch.
YELLOW- Double Density- yellow double density is often labeled as "Gas type"
RED-Triple Density: (Note-the container is red but the tape itself appears as a pale pink color). Presently required on all joints ½" diameter or greater.
GREEN- Oil Free PTFE tape- Required for use on all lines conveying oxygen (I.E. medical oxygen or welding oxygen lines).
COPPER COLOR- contains granules of copper and is to be used as a thread lubricant but is
not approved as a thread sealant. (Generally it is used as a thread lubricant on bolts
or pipe threads for mechanical applications where no physical seal is required.)

PTFE tape is only approved as a thread seal when applied correctly. To apply you begin at
the end of the pipe and wrap the tape under tension in the direction of the thread turns.
Each successive layer should overlap the previous layer by ½ to 2/3 and continue wrapping
until the entire threaded portion of the pipe is covered. (Minimum of 3 full turns).
