VIEGA pipe connector with tapered seal 16 mm to 3/4" male thread, model 7548442

VIEGA pipe connector with tapered seal 16 mm to 3/4" male thread, model 7548442 is designed to provide a secure transition between a 16 mm pipe and a standard 3/4" male threaded fitting. The connector features a tapered sealing seat that ensures reliable contact with the mating component and creates a watertight joint suitable for plumbing and heating systems. It is intended for use with small-diameter copper or plastic pipework where a threaded appliance, valve, or fitting must be attached.

Advantages

The tapered sealing seat delivers a consistent compression surface that improves sealing reliability compared with flat-seat adapters. The connector's dimensions are matched for common 16 mm tubing and standard 3/4" male threads, allowing straightforward installation without special adapters. Its design supports use in water supply and heating circuits and is suitable for repair and retrofit applications where a dependable threaded connection is required.

Suitable for

• Connecting 16 mm copper or plastic pipe to a 3/4" male threaded valve or appliance
• Domestic water supply lines and branch connections
• Heating circuit connections and radiator fittings
• Repair, maintenance, and retrofit plumbing work

Key specifications

• Connection A: 16 mm pipe interface with tapered sealing seat
• Connection B: standard 3/4" male thread
• Sealing type: tapered (conical) seat for mechanical seal
• Application: potable water and heating systems
• Typical materials: corrosion-resistant metal alloy suitable for plumbing use

How to use

Cut and prepare the 16 mm pipe end to ensure a clean, square face. Insert the pipe into the connector until it seats against the tapered sealing surface, and secure according to the connector's assembly method (compression, crimping or threaded coupling where applicable). Engage the 3/4" male thread to the mating female thread and tighten to the recommended torque for the thread size, ensuring the tapered seal seats without distortion. After assembly, pressurize the system and inspect the joint for leaks.

Usage recommendations

Use compatible pipe materials and fittings rated for potable water or heating applications; verify thread compatibility and follow local plumbing codes. Avoid over-tightening the 3/4" connection to prevent damage to the tapered sealing seat. If intended for use with a specific sealing method (olive, compression or crimp sleeve), use the matching components and tools to achieve a reliable joint.
