Thermostatic cartridge FERRO RKPT1-C7 M30x1.5 for 39 mm profile manifolds

Thermostatic cartridge FERRO RKPT1-C7 with M30x1.5 thread is designed for mounting in 39 mm profile manifolds. It functions as the regulation element in heating distribution assemblies, controlling flow and temperature in underfloor heating and radiator manifold systems that use FERRO 39 mm spacing profiles. The cartridge is compatible with systems that accept an M30x1.5 threaded thermostatic insert and is intended as a replacement part for accurate hydraulic and thermal regulation.

Advantages

The thermostatic cartridge provides precise flow and temperature control within the manifold thanks to its threaded M30x1.5 connection and compact design for 39 mm profile manifolds. It enables stable hydraulic balancing and straightforward replacement without modifying the manifold. The part is built to integrate with standard heating distribution components and helps maintain consistent room temperatures by reacting to valve setpoints.

Suitable for

• Underfloor heating manifolds with 39 mm profile spacing
• Radiator manifold systems using FERRO-compatible components
• Replacement of worn or damaged thermostatic cartridges with M30x1.5 connection
• Heating distribution assemblies requiring precise flow/temperature regulation

Key specifications

• Thread type: M30x1.5
• Compatibility: designed for 39 mm profile manifolds
• Function: thermostatic regulation element for flow and temperature control
• Application: underfloor heating and radiator manifold systems

How to use

Turn off the heating circuit and isolate the manifold before removing the existing cartridge. Unscrew the old thermostatic cartridge from the manifold socket and inspect the seat and sealing surfaces for debris or damage. Screw the FERRO RKPT1-C7 cartridge into the M30x1.5 threaded port by hand and then tighten to the manufacturer's recommended torque. Refill and vent the system, then restore normal operating pressure and check for leaks. Adjust the valve or thermostat setpoint and verify that flow and temperature control respond correctly.

Usage recommendations

Use only in manifolds with 39 mm profile spacing and M30x1.5 threaded ports. Replace cartridges with identical thread and functional characteristics to preserve hydraulic balance. If uncertain about installation or torque values, consult the manifold manufacturer’s instructions or a qualified heating technician.
