## Summary description

INVENA reduction fitting ZR-20-403 in black is a pipe connector designed to join pipes of different diameters (3/2" to 1"). It provides a compact mechanical transition between two pipe sizes for plumbing installations. Suitable for use in residential and commercial water systems where a diameter reduction is required; compatible with standard threaded piping.

## Long description

INVENA reduction fitting black 3/2 x 1" ZR-20-403 is a compact pipe connector designed to create a secure mechanical transition between a 3/2" pipe and a 1" pipe. Constructed to fit standard threaded piping, this reduction fitting enables a reliable diameter change in plumbing systems where space is limited. The black finish provides a discreet appearance and may be used in visible installations without drawing attention.
Advantages
The fitting offers a straightforward threaded connection that simplifies installation and maintenance. Its compact design reduces the amount of space needed for the diameter change, and the black surface helps conceal the connector in installations with visible piping. The component is compatible with common water system materials and provides a stable, leak-resistant joint when installed correctly.
Suitable for
Residential plumbing where pipe diameter reduction is required
Commercial water supply installations with standard threaded pipes
Repair or modification of existing piping systems
Tight spaces where a compact connector is preferred
Key specifications
Function: reduction fitting for joining two different pipe diameters
Connection type: threaded male/female transition compatible with standard threaded pipes
Sizes: reduces from 3/2" to 1"
Finish: black surface for discreet appearance
Application: potable water and general plumbing systems
How to use
Before installation, ensure both pipes are clean, free of debris and the threads are intact. Wrap thread sealant tape or apply suitable thread sealant to the male threads to ensure a watertight connection. Hand-start the fitting onto the thread to avoid cross-threading, then tighten using an appropriate wrench until snug; avoid excessive torque to prevent damage to threads or fitting. After installation, pressurize the system and inspect the joint for leaks. Re-tighten slightly if a minor leak is detected or disassemble and reapply sealant if necessary.
Usage recommendations
Use compatible thread sealants and follow local plumbing codes. Avoid overtightening and ensure the materials of connected pipes are suitable for a threaded metal/plastic interface. For critical or concealed installations, consider pressure testing after installation and periodic inspection as part of routine maintenance.
