What do I do if the seals on my Easy Seal hoses leak?
⌄
Malco sells replacement gaskets so you can replace them in the field and extend the life of your hoses. SSG14 fits both the 1/4″ and 5/16″ Easy Seal fittings.
Q2
Does hose length matter when pulling a vacuum?
⌄
Does hose length matter when pulling a vacuum?
⌄
Yes. Shorter hoses with a larger diameter — such as a 3/8″ MalcoEdge Turbo Flow hose — are more efficient when pulling a vacuum.
Q3
Can I use the same hoses with a variety of refrigerants?
⌄
Can I use the same hoses with a variety of refrigerants?
⌄
MalcoEdge hoses are compatible with popular refrigerants. However, we do not recommend using multiple refrigerants in the same hoses unless you flush them first using a product like ACE Powerflush. To prevent cross-contamination from oils left in the hoses, we recommend dedicating separate hoses to specific refrigerants.
Q4
Do I need to flush and clean my equipment when switching between refrigerants?
⌄
Do I need to flush and clean my equipment when switching between refrigerants?
⌄
Yes. Some refrigerants use different lubricants and cannot be mixed. As a best practice, flush hoses, manifolds, and other components between services to prevent cross-contamination. We recommend using ACE Powerflush when switching refrigerants.
Q5
What are the working and burst pressures for these hoses?

Working pressure is 800 PSI. Burst pressure is 4,000 PSI.
Q6
What do I do if my hoses engage a Schrader valve too early or not enough?
