Tube Fittings help overcome alignment problems.

Press Release Summary:



Featuring spherical or semicircular contact surface, Tru-Fit Tube and Pipe Fittings allow connections to be made from various radial axes. Male and female connections are similar to ball and socket construction, which allows connections to swivel prior to tightening. Units may include fitting, nut, and tube flare or ferrule, all of which are circular. If 2 objects being connected are offset, fittings could eliminate need to bend tube or pipe.

Tru-Fit Alignment Fittings Overcome Many Limitations of Prior Fitting Designs


Alignment has always been a major problem in connecting objects using tube or pipe fittings. Now you can have true alignment without being in line.

Tru-Fit Alignment Fittings overcome many limitations of prior fitting designs.

Prior designs allow for one directional alignment at point of contact between the fitting and the mating part. If the two objects being connected were offset then bending of the tube, pipe, or rod would need to be done in order to properly align the two objects.

With this process there is always stress (tension) within all parts used, including the two parts being connected. There will be either a pushing or pulling force between the two objects. The tubes, pipes, or rods always have variables which make it impossible to produce two parts exactly alike.

Even with the standard tolerances given in the manufacturing process there is still stress created when the connection is made. Some of these variables are wall thickness variation, material hardness, diameter variation, and length of part variation.

These variables add to the amount of stress created in the connection. The two objects being connected are most likely to be stationary so the flexibility must come from the tube and or fittings. Prior designs limit this greatly needed flexibility.

The Tru-Fit tube fittings and pipe fittings allow connections to be made from various radial axes. It has a unique contact surface which is spherical or semicircular in nature. Male and female connections are similar to a ball and socket construction which allows the connections to swivel prior to tightening. It may include a fitting, nut, and a tube flare or ferrule, all of which are circular in nature.

Tru-Fit tube fittings and pipe fittings allow for a multiple of directional alignments at point of contact between the fitting and the mating part. If two objects being connected are offset, using the Tru-Fit design fittings could eliminate the need for bending of the tube or pipe.

One reason for bending would be to navigate around other objects between the two being connected. By using Tru-Fit fittings on both ends of the tube or pipe, and another somewhere in between, stress in and between the two objects connected would not occur.

Tru-Fit fittings allow much more tolerance between the two objects being connected. Telescoping tube configurations using Tru-Fit tube and pipe fittings may also be used.

With the use of Tru-Fit Alignment tube and pipe fittings the following may be obtained:

1. Tru-Fit Alignment tube and pipe fittings can produce stress-free connections between two objects being connected.

2. Any radial axis connection can be made using a male Tru-Fit Alignment fitting with a female Tru-Fit Alignment nut.

3. With the use of Tru-Fit Alignment fittings there may be no pushing or pulling force between the objects being connected.

4. Tru-Fit Alignment fittings will allow greater dimensional tolerances between objects to be connected.

5. The use of Tru-Fit Alignment fittings and nuts may in some cases eliminate the need for bending of the tube or pipe.

6. Tru-Fit Alignment fittings and nuts may mate with a flared tube of a prior design and still have the rotating axis.
