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?
