ULN400 - Genuine OEM Master Plumber Faucet Aerator, Dual Thread, Chrome

ULN400 - Master Plumber Faucet Aerator, Dual Thread, Chrome

The ULN400 Master Plumber Faucet Aerator is a premium OEM-quality dual-thread faucet aerator with a chrome finish, designed to help improve faucet water flow, reduce splashing, and provide a more controlled water stream. AMRE Supply identifies the ULN400 as an OEM-quality aerator featuring a 15/16" male end and a 55/64" female end.

The dual-thread design makes the ULN400 suitable for compatible faucet configurations using either thread arrangement. AMRE Supply specifically lists the 15/16" male end for American Standard and Delex faucets and the 55/64" female end for Waltec and Emco faucets.

Available from Appliance Kingdom in Canada, this faucet replacement part is suitable for homeowners, landlords, property managers, maintenance professionals, and plumbing technicians looking to replace a worn or damaged faucet aerator.

What Does the ULN400 Faucet Aerator Do?

A faucet aerator attaches to the end of a faucet spout and helps shape and control the water stream as water leaves the tap. The ULN400 uses a dual-thread configuration to accommodate compatible faucet connections while helping produce a more controlled flow.

A properly functioning aerator can help reduce water splashing around the sink and improve the feel of the water stream. The ULN400 is listed as a premium dual-thread aerator and is specified with 15/16" male and 55/64" female threads.

Using the correct thread size is important. Even if an aerator looks similar to the original component, an incorrect thread configuration can prevent proper installation or result in an unsuitable connection.

Common Signs Your Faucet Aerator Needs Replacement

A faucet aerator may need replacement when you notice:

• Uneven or irregular water flow

• Water spraying or splashing excessively

• A poorly shaped water stream

• Reduced or inconsistent flow from the faucet

• Mineral deposits or debris affecting the water stream

• A damaged or worn aerator

• An aerator that no longer threads securely onto the faucet

If the problem is caused by the aerator itself, replacing it with the correctly sized ULN400 can restore proper water-stream performance. If the faucet has an internal cartridge, valve, supply-line, or plumbing problem, replacing the aerator alone will not correct that underlying issue.

Will Replacing the ULN400 Fix My Faucet Problem?

It can if the aerator is responsible for the poor or irregular water flow.

A clogged, damaged, or worn aerator can interfere with the water stream at the faucet outlet. Replacing the aerator can restore the intended outlet flow when the aerator is the source of the problem.

Before ordering, compare the thread configuration and size of your existing aerator with the ULN400 specifications.

Compatibility & Ordering Guidance

The ULN400 is a faucet aerator with:

• 15/16" male thread

• 55/64" female thread

• Dual-thread configuration

• Chrome finish

• 27 TPI specification documented by AMRE Supply

AMRE Supply specifically states that the 15/16" male end fits American Standard and Delex applications, while the 55/64" female end fits Waltec and Emco applications.

Always verify the thread size and configuration of your existing faucet before ordering. Faucet appearance alone is not sufficient to confirm compatibility.

If you are unsure, provide the faucet brand, complete faucet information, or a photo and measurements of your existing aerator to Appliance Kingdom for compatibility assistance.

Installation Overview

Replacing a faucet aerator is generally a simple repair that can often be completed by an experienced DIYer.

The basic process involves removing the existing aerator from the faucet outlet, cleaning the faucet threads and outlet area, checking the new aerator's thread configuration, and installing the replacement without overtightening.

Because the ULN400 has dual-thread connections, confirm whether your faucet requires the 15/16" male or 55/64" female configuration before installation.

Professional plumbing assistance is recommended if the faucet connection is damaged, seized, leaking, or difficult to remove without risking damage to the faucet.
