Plumbing and Assembly Hints
Even after choosing the appropriate type of fitting for your ap-
plication, there are certain instances when a particular style has
advantages over others.
1. Straight thread adjustable elbows and tees have several
advantages over similar shaped fittings using tapered pipe
threads:
Adjustable straight thread connections:
• Permit exact positioning
• Provide leak free joint
• Eliminate distortion and cracking of boss due to over-tight-
ening
• Are easier to maintain

– allows for 360° positioning of fitting without losing its sealing
capability
2. Swivel nut fitting should be used with a straight connector
to allow for connections in tight spaces, where an elbow or
tee fitting cannot be fully rotated (see Fig. T59).
This same combination of fittings, shown in Fig.T59, can also be
used to stack tube lines or provide clearance for ports that are
relatively close and within the same plane (see Fig. T60).

nector in tight space

3. Use reducers/expanders and jump size fittings.
There are some instances when it becomes necessary to
connect tube lines of different sizes or tube lines to ports
of different sizes. This can be accomplished by using either
tube reducers, port expanders, port reducers, or jump size
fittings. Achieving the reduction or enlargement is the main
concern, but this should be accomplished by using the
minimum number of connections (potential leak points and
wrenching requirements) possible.
4. Use conversion fittings and adapters.
There are instances when it becomes necessary to use
conversion adapters for connecting a fitting to a port with
different style threads, for example, UNF thread fitting to a
metric thread port. There are also some instances when it is
necessary to connect tube ends or hose ends with different
style terminations to one another or to a fitting. This can be
achieved by using conversion fittings.
5. Use of other adapters and fittings for special applications
are shown below.
