FAQs
Q: What do I do if the seals on my Easy Seal hoses leak?
A: Malco sells replacement seals to allow you to replace your seals in the field and
extend the life of your hoses.
Q: Does hose length matter when pulling a vacuum?
A: Yes, the shorter the hose and the larger the diameter, such as a 3/8″ MalcoEdge
Turbo Flow hose will be more efficient when vacuum is pulled.
Q: Can I use the same hoses with a variety of refrigerants?
A: MalcoEdge hoses are compatible with popular refrigerants however we do not
recommend using multiple refrigerants in the same hoses unless you take the time
to flush the hoses using a product such as ACE Powerflush. Alternatively, we
recommend you use different hoses for specific refrigerants to prevent cross
contamination of refrigerants from oils remaining in the hoses.
Q: Do I need to flush and clean my equipment when switching between refrigerants?
A: Some refrigerants cannot be mixed as they use different lubricants. As a best practice,
the hoses, manifolds, and other components need to be flushed using a cleaner to ensure
they do not cross contaminate. We recommend flushing the system with ACE Powerflush
between services.
Q: What are the working and burst pressures for these hoses?
A: The working pressure pressure is 800 PSI and the burst pressure is 4000 PSI.
Q: What do I do if my hoses are either engaging a Schrader valve too early or not
engaging a valve enough to fully open the valve?
A: The core depressors are threaded. Adjust the height of the core depressor by screwing
further in or out.
Q: Do the MalcoEdge Safe Seal hoses vent to atmosphere when disconnecting the hoses
from the service port?
A: No, the core depressor when retracted seals the refrigerant in the hose.
