Recoverable Fitting Technical Guide

Terminology - Piping Fabrication - Fitting Assembly

Pipes:

Pipes are conduits that can be made of metal, plastic, or rubber.

Fittings:

Fittings are metal pieces that are attached to the ends of pipes to allow them to connect to other pipes or devices.

They belong to three main families:
A: with inner rubber lining meeting SAE 100 standards: R1AT - R5C - R5R.
B: with inner thermoplastic lining: TTA - TTK.
C: with inner PTFE lining such as THP1.
The reinforcement (or reinforcement carcass) of the one or the other is composed of:
- one or more textile braids.
- a steel braid.
- combination of two of these formulas.
This architecture is defined in the presentation text of all our listed hoses (Hydraulic Hose Catalogue).

Nipples:

Zinc-plated and double-chromated for the standard: they can be supplied, upon request, in stainless steel.
Depending on the desired equipment and the pipe used, they have a different back part depending on the mode of anchoring on the pipe.

Screw Fittings for Pipes: T510 - T511 - T111	Teflon Fittings for Pipe: THP1

Pipe Cutting:

T111 - T510 - T511:
Cut square with a very fine toothed metal saw (or preferably a chainsaw), moderately clamping the pipe in a vice.
TPH1:
Same procedure as above, but prewrap the pipe with adhesive tape at the cutting line, so as to avoid the braid from "frizzing".
TTA - TTK:
Cut the pipe squarely with a sharp, fine blade or with a Ref 28908631 Metal Cutting Pliers (Tecalemit Flexible Pipe Pneumatics Catalogue).
Our cutting and stripping machines save a lot of time and ensure a neat, perfectly square cut, without any effort from the operator.

Assembly of recoverable fitting :

FOR T111-T510-T511

The fitting of the hose end is done on the covering of the pipe that must not be stripped
The length to be stripped is determined on each socket by the measurement between its rear face and a mark engraved on its exterior.
Brush braid or sheet before mounting the fittings.
Moderately tighten the socket in a vice.
Screw the pipe into the socket (left-hand thread) to the stop.
Then unscrew a quarter turn (important).
Abundantly oil the inside of the pipe and the part of the nipple intended to penetrate it (nipple).
Screw the nipple into the socket (right-hand thread) until the six corners of this nipple are 0.5 mm from the front face of the socket.

Orientation of Ends:

The angle of orientation of the ends is that chosen by convention in the following way:
A: Look at the piping from the front by any of its ends.
B: Starting from the nearest end and turning counterclockwise, consider the angle formed with the second end.
Tolerance on the angle of orientation according to the length T:
Length T ≤ 610 tolerance = ± 3°
Length T > 610 tolerance = ± 5°
