Compression Fitting PEX Female Thread 3/4" x 16x2 Varioterm — black matte

Varioterm compression fitting PEX Female Thread 3/4" x 16x2 in black matte provides a compact mechanical transition between 16x2 mm PEX piping and 3/4" female threaded fixtures or components. Designed for use in potable water and heating systems, the fitting uses a compression sleeve to create a sealed connection without the need for soldering or adhesive. The black matte finish offers a discreet visual profile where the fitting remains visible in installations.

Advantages

The fitting creates a reliable, leak-resistant connection by compressing a sleeve onto the PEX tube, ensuring mechanical stability and consistent sealing. Its design supports quick installation with common hand tools and eliminates thermal stress associated with heat-based joining methods. The compact form factor and matte black surface reduce visual contrast in visible installations and are suitable for tight spaces where a manufactured transition from PEX to a threaded connection is required.

Suitable for

• Connecting 16x2 mm PEX pipes to 3/4" female threaded valves, taps or appliances
• Domestic potable water distribution systems
• Residential and commercial heating circuits using PEX piping
• Retrofit or repair jobs where a compact PEX-to-thread adapter is needed

Key specifications

• Connection types: 16x2 mm PEX to 3/4" female thread
• Joining method: compression sleeve sealing
• Material finish: black matte
• Application: potable water and heating installations
• Mounting: push-on PEX with compression nut and ferrule

How to use

Prepare the PEX tube by cutting it squarely and deburring the cut end. Slide the compression nut and ferrule onto the tube, insert the tube fully into the fitting body until it seats against the internal stop, then tighten the compression nut by hand and finish with a suitable wrench to the manufacturer’s recommended torque. Thread the 3/4" female side onto the corresponding male threaded component and verify alignment. After assembly, pressurize the system and inspect the connection for leaks before finalizing insulation and concealment.

Usage recommendations

Use with compatible 16x2 PEX tubing and ensure all sealing surfaces are clean. Avoid over-tightening the compression nut; follow tool and torque guidance to prevent damage to the ferrule or PEX tube. Confirm that the black matte finish is acceptable for any visible installation areas and protect against prolonged UV exposure if installed outdoors.
