Pipe reducer INVENA ZO-20-251, galvanized steel, 1" x 1/2"

Galvanized steel pipe reducer INVENA ZO-20-251, size 1" x 1/2" provides a durable transition between pipes of different diameters. Intended for plumbing and heating systems, the reducer connects male and female threaded fittings to ensure a secure mechanical join and maintain flow continuity where a reduction in diameter is required. Corrosion-resistant galvanized finish helps extend service life in typical residential and commercial environments.

Advantages

The reducer is made of galvanized steel for improved resistance to rust and surface degradation. Its threaded male-to-female design ensures straightforward installation with standard threaded pipe fittings. The compact form factor and solid construction deliver reliable mechanical strength under normal plumbing and heating operating conditions. The product is compatible with common pipe materials used in domestic and light-commercial installations.

Suitable for

• Reducing pipe diameter in domestic water supply lines
• Adapting connections in heating and radiator systems
• Plumbing repairs and retrofit work where threaded connections are used
• Commercial installations requiring a reliable mechanical reducer

Key specifications

• Material: galvanized steel
• Size: 1" x 1/2" (male-to-female threaded reducer)
• Thread type: standard pipe threads for threaded fittings
• Finish: galvanization for corrosion resistance
• Application: plumbing and heating systems

How to use

Before installation, verify that the thread sizes and types on mating fittings match the reducer. Clean threads on both the reducer and mating pipes to remove debris or old sealant. Apply an appropriate thread sealant or PTFE tape to the male threads to ensure a leak-tight joint. Hand-start the reducer onto the fitting to avoid cross-threading, then tighten with a wrench until secure; do not overtighten to prevent thread damage. After installation, pressurize the system and check for leaks at the connection, re-tightening slightly if necessary.

Usage recommendations

Use the reducer within the recommended temperature and pressure limits of the piping system. Avoid using galvanized fittings in systems with aggressive chemicals or where galvanic corrosion with dissimilar metals could occur without proper mitigation. For critical applications, consult system specifications and local plumbing codes to confirm compatibility with materials and threads.
