SPCAll fluids
Applications
Machine tools :- Connection and
disconnection of machining heads
- Hydraulic clamping and palletisation…
Cooling:- Inserts and modules on moulds
- Electronics
5 diameters available: 3, 5, 8, 12 and 20 mm
Pollution-preventing flat faced design ensures fluid integrity- No introduction of air or contaminants
into your circuits
- No pollution of the working area
- Cleaning facilitated before connection

Perfectly designed…
Floating on both sides: interface 0 Rigidly installed plug: interface 0 or 4.2 mm
Socket and plug recessed into pocket and fixed onto the machine by elasticated ring.
Socket recessed into pocket and plug screwed into the machine with O ring sealing.
2 possible installation options for complete integration into the machine
ReliabilityThe SPC is designed for high frequency use of up to 1 million connections.
EfficiencyThe SPC range is compact and guarantees an excellent flow for minimal outside dimensions, whatever the direction of flow.In addition, the SPC maintains full flow even if the coupling is not fully connected. This tolerance is 2 mm.
Recessed installation into pocket provides the minimum outside dimensions.In addition, in the case of floating installation, 0 interface between plug and socket represents extra space saving.Due to the 2 installation options, the SPC can be adapted to all your needs.

… to fully integrate with your machine
Take up of misalignment on connection- A form of preguiding combined with an elasticated connection permits a take-up of misalignment between plug
and socket on connection.
- To ensure take up of misalignment on connection, the pocket centres must be within the diameter of circle a.

Operating temperatures depending upon the type of seal**
Types of seal Operating temperatures
Nitrile (NBR) - 15 to + 100 °
Fluorocarbon (FPM) - 10 to + 150 °
Ethylene-Propylene (EPDM)*** - 20 to + 150 °
For use outside the indicated temperature ranges: consult us.
** The minimal temperatures of use are given for static conditions and exempt from mechanical stress.
Sealing
3 types of seal:- Nitrile (NBR) - Fluorocarbon (FPM)- Ethylene-Propylene (EPDM)***
*** Important! The use and any contact of this seal with fluids of mineral origin (oil, fat…) is highly inadvisable.
ConstructionHigh resistance stainless steel.
