Can Python be buried?
Yes. The Python Line Set product can be used for underground buried applications with sand, dirt, or concrete. Do not bury with a gravel or rock media. The outer PE-RT layer cannot be cut or damaged exposing the inner aluminium layer underground or to the atmosphere. Fittings should not be buried at any time.
Can you run refrigeration flushing fluids through Python?
Yes. Independent tests have been using flushing fluids.
Is the Python Line set UV resistant?
Yes.
Can Python be used on heat pumps?
Yes
Is the copper flare gasket required to be used with the female fittings?
Yes
Can Python Pipe be cut with aftermarket tubing cutters?
Yes, be sure that the cutting wheel is large enough to cleanly cut through all three layers of the Python pipe.
Is the Python chamfering tool the only way to chamfer the pipe?
Yes, the Python chamfering tool are designed exclusively for the Python pipe.
How do I know if the python pipe is inserted into the fittings?
The Python chamfering tool has a reference shoulder on the tool, which is used to mark the insertion depth. (Please see the Python Line set Installation Guide)
I don’t have a torque wrench; can I just wrench it tight?
Yes, the Python fittings are designed to be tightened until the nut bottoms out on the adapter body.
Can I use a tube bender on Python?
Yes, but since the OD of the Python lines is larger than that of copper, when using crossbow benders, you’ll need to use one size up. (Also, the 1/4” and 3/8” Python are the same OD and will require the use of the ½” half-moon)
What is the minimum bend radius?
1/4” and 3/8” 38.1mm
1/2” 57.15mm
5/8” 63.5mm
3/4” 69.85mm
7/8” 152.4mm
Will Python kink?
While Python is less likely to kink than copper, it is susceptible to kinking once the minimum bend radius is exceeded.
If the pipe is nicked during installation, should it be used?
The outer layer of the Python line set pipe can be nicked during the installation process as long as the aluminium is not fully exposed. If the aluminium layer is visibly exposed, then the damage section of the pipe should be replaced.
Can you attach temp probes to the Python line to measure refrigeration temperature?
No. Since the Python line have multiple layers which gives the product a slight R value, it’s not recommended to make refrigerant measurements directly on the Python line.
Can Python fittings be reused?
No, once the Python pipe is inserted onto the nipple and nut is tightened the pipe can’t be removed from the fitting.
Does the through hole of the fittings cause any restriction in flow?
No. The Python line set fitting orifice does not cause any refrigerant flow restriction. The pressures and temperatures were comparable for both the Python refrigeration loop and the copper refrigeration loop on the same HVAC system.
