Introduction.
Aflex Hose have developed a revolutionary new concept for end fitting attachment for their Pharmaline and Pharmalex hose products which can be easily assembled by customers on site, using a simple manually operated hydraulic press. It is called Relink.
The same press can also be used to disassemble the end fitting, in order that the main components can be reused.
The concept of reusable self assembly end fittings is not new, and several designs have been available for many years, but they have never been a complete success. This is due to difficult and unreliable assembly methods, the high cost of components, and the lack of availability of a wide range of fitting designs. The new Relink End Fitting design overcomes these problems, and offers many other important technical advantages.

Advantages of the Relink End Fitting System.
Uses Standard Aflex End Fitting Inserts.
Relink can be used to assemble all the standard end fittings, including Sanitary Clamp (Triclover) fittings, ensuring ex. stock availability of many different types of fittings.
Reliable Joint.
Other self assembly, reusable fittings all include screwthreads, which can be over-tightened, or under-tightened, and often have low “blow-off” pressure ratings. Relink fittings do not use screwthreads, and always provide a positive, pressure tight joint.
Hygienic Design.
The patented system applies a non rotating radial pressure to the hose without any “screwing” of the end fitting, so a true hygienic joint can be made when used with Aflex hygienic end fittings.
Tamper-Proof.
Other reusable/self assembly designs, can be accidentally loosened or disassembled manually or with a spanner during or after connection in the application. The Relink End Fitting can only be dissassembled using the Relink Press, after disconnection from the application. |

Note: Hose assemblies with Relink fittings are not electrically continuous (not 'EC'). Only Pharmaline Hose assemblies
with crimped fittings are electrically continuous.
EXAMPLE: A Relink Triclamp Assembly.
|
The Relink Triclamp components and the hose are assembled, and inserted into the Press by encapsulating the groove in the Compression Sleeve between the two Slide Plates as shown.
The Press Triclamp Adaptor is then pressed down, to engage the Triclamp Fitting Insert and commence compression.
When the Compression Sleeve touches the shoulder on the Fitting, the assembly is completed. The Adaptor is reversed, freeing the assembled fitting for removal by sliding out of the Slide Plates.
To recover the Fitting, the hose is cut off at the back of the Fitting, and the Triclamp Fitting Spigot is pressed out, using the Press and a Relink Extraction Tool. The Sleeve and Spigot are then available for re-use. |
