Although you might not think of it right away, assuring adequate
tube line support is critical to keeping hydraulic, pneumatic or
lubrication systems efficient, leak-free and easy to maintain. Once

Most people are aware that hydraulic fittings such as 37° Flare
(JIC), O-Ring Face Seal, or Metric Flareless (DIN) tube fittings
are designed to industry standards, such as SAE J514 or ISO...

Wouldn’t it be nice if leak-free connections could last
forever? Nice, yes, but not exactly realistic. The good news
is that fitting designs have improved significantly over time,
making it easier to...

Not all BSPP 60° cone fittings are created equal, nor are they
always interchangeable. Questions often arise regarding
compatibility and interchangeability between different kinds of
BSPP 60° cone...

Hydraulic systems using properly sized tube will perform more
efficiently and cost-effectively. Tube that is too small can
increase fluid velocity causing pressure drops and heat generation,

Industrial machines and equipment are designed and manufactured in
every corner of the world. The hydraulic systems alone use
countless different types of fittings and adapters with different

What’s so bad about a few drops of oil? Try this: Three drops of
oil a minute leaking from one connector in your hydraulic system
will cost you $168 a year just in replacement oil. And how...
