Do you have any advice for people relative to buying or using tube fittings?
24 answers
Yes, low pricing usually is a main driver for selecting a tube fitting supplier. I'd suggest making sure quality is up to snuff, as a low price today won't lead to lowest long term cost for upkeep. If OEMs sell a quality system, don't be scared to pay for a quality product.
~Jeff K, Marketing/Sales, Atlanta, MN
Cheapest isn't always best. You get what you pay for. (beware low cost imports) Buy your tubing from the same manufacturer as the fittings, this way you are assured the same quality standards are used.
~Robert Keller, Marketing/Sales, Suwanee, GA
Do not skimp on the fitting specification wrt line pressure specify correct material for process conditions match threads to avoid unsealable leaks use proprietary sealant on high pressure lines
~P J O C, Engineering Consultant, Cork, Ireland
Know the products you are using, what is the cleanliness level for fittings? What kind of application you have, need an increased corrosion resistance, temperatures in the system?
~Sampsa V, Technical Support, Jyväskylä, Finland
If not familiar with products read up on it, plenty of information available, know application details, etc working pressure, medium conveyed, thread types.

Decide the thread types that suit your needs and stick to it mix and matching between metric and imperial fittings costs a premium.
