Though often underestimated, tube end preparation is one of the
most critical processes in obtaining an optimum seal of any
flanged, brazed, flared or preset tube end connection. When

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

Hydraulic, pneumatic or lubrication systems should be efficient and
leak free. Sometimes, they are not, because of improper tube line
routing—the result of either lack of knowledge, or corners cut...

Question: So, does it really matter which technique you choose? In
front of you is an NPTF tapered thread assembly. The recommendation
is to ‘turn,’ not ‘torque,’ to assemble the connection. But all...

Myth and misapplication are abundant when it comes to hydraulic
fitting leaks. From small operations to global corporations, we’ve
seen and heard it all. Let’s clear up some misconceptions....

A $1 hydraulic fitting can ruin a $10,000 valve or other expensive
component(s) in your system. Microscopic metal flakes that fall off
tube fittings during installation can travel through the...

As engineers, we know that it pays to plan ahead. There
simply isn’t a better business rule that will help us save time and
money, avoid problems down the road or just build a better

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...
