Compressor gets hot and blows line

That sounds like your main regulator is not plumbed correctly.
On the regulator there is an arrow on one of the ports. The high pressure tubing must go into the port that is at the tail end of the arrow, and only that port. The other three ports are kept at working pressure ~60psi.

We are pressurizing 3 of the 41in^3 tanks.

The setup

VI Compressor-->Tanks (with pressure switch, and pressure gauge installed on the tanks -->Regulator (60 psi) ----Splits to two paths

Path A: ---> 30 psi regulator -->solenoids
Path B: ----> Solenoids

Let me check the regulators, and get back to you.

Like many have said, we always use lots of brass fittings at the beginning of the line from the compressor and put the required fittings on there as well, this helps because the brass dissipates the heat before it reaches the tubing.

Reverse the polarity to the compressor?

Matthew,
Is this the same robot you are asking about in the Labview Forum? If so, there is something seriously wrong with the DSC or your code. The compressor should not come on until the robot is enabled. Neither should the RSL.
