Delcop Monument Pipe End Cleaner 1968

Monument have always strived to make a professional a quality pipe end cleaner and since the 1960s Monument Tools has designed, manufactured and marketed professionally quality pipe end cleaners.

The original drawings from 30th January 1968 are shown indicating there always has been a need to provide a pipe end cleaner for copper pipe ready for soldering.

Later into the 1980s Monument manufactured the 364C Pipe End Cleaner, again #MadeInBritain. Subsequently Monument sold the DBB1522 15mm and 22mm Cleaning and Deburring brush.

DBB1522 and 364 Pipe End Cleaners

More recently Monument had success with the CopperKey 2915Q and 2922M made in the USA featuring both a brush for cleaning fittings and a pipe end cleaner

As we move into a world of social media and the desire for heating engineers, gas engineers and plumbers to create and post their quality workmanship seemingly the need for a 21st Century pipe end cleaner is here. Monument has designed and marketed a new version the MAST20259P Monument Masters Professional Quality 15mm and 22mm Pipe End Cleaner

Frequently asked Questions FAQ :

Use on soldered joints :

Why remove the oxide or surface from a copper pipe for a soldered joint?
Removing oxide (tarnish or patina) from a copper pipe ensures a flawless, leak-free soldered joint, as oxides prevent solder from properly adhering to the metal. It also reveals the underlying metal so you can inspect for hidden pinhole leaks and restores a polished, professional appearance.

Use on compression fitting joints :

Why remove the oxide or surface from a copper pipe from compression fittings ?
Removing the oxide layer (often called tarnish or patina) from a copper pipe is critical before installing a compression fitting because the fitting’s brass “olive” (ferrule) must bite directly into clean, bare copper to create a reliable, watertight seal.

Use on Push Fit Fittings :

Why remove the oxide or surface from a copper pipe?
Removing oxide from a copper pipe ensures a flawless, leak-free seal with push-fit fittings. Oxidation creates a rough, uneven surface that prevents the fitting’s internal O-ring from gripping properly, and it can eventually corrode the seal.

Use on Crimped Fittings :

Why remove the oxide or surface from a copper pipe?
Removing oxidation from copper pipe before applying crimp (press) fittings ensures the O-ring creates a perfect, long-lasting watertight seal

The oxide removal process is critical for three main reasons:

O-Ring Integrity: Crimp fittings rely on a synthetic rubber O-ring to seal the joint. Oxidation creates a rough, crusty, or uneven surface that can act like sandpaper. If the O-ring scrapes across this oxidized layer during insertion, it can become nicked or compromised, leading to slow leaks.
Metal-on-Metal Grip: When the crimping tool crushes the fitting, the metal of the fitting compresses directly into the copper pipe. Heavy oxide, corrosion, or scale (like green patina) acts as a physical barrier. Cleaning the pipe down to bare, shiny copper ensures the fitting bites into the actual pipe wall, preventing it from slipping or weeping under pressure.
Surface Imperfections: Sometimes, thick oxide hides minor scratches, manufacturing stamps, or debris on the copper surface. Cleaning the pipe allows you to inspect it for deep scores or nicks that could breach the O-ring seal, which would require the pipe to be cut and re-prepped

Galvanic reactions in oxide layers

Sometimes accelerated galvanic degradation frequently occurs at the boundary between two different metal oxides due to galvanic effects between the underlying base metals, or when an oxide layer breaks down in the presence of an electrolyte, if you ensure a good joint Mechanical or Soldered you can prevent the appearance of the electrolyte and hence the opportunity for corrosion can be minimised.
Examples In plumbing dissimilar metals could be Copper/Brass, Copper/Steel, Copper Iron, Copper Stainless Steel, Copper/plated fittings such as Nickel or Chrome or Zinc.

How do you use a Monument AutoBrush® ?

The Monument Tools Autobrush® can be use by hand or using a electric rotary drive tool such as a cordless drill, with a 3/8” Square drive bit.

DOs

DO use the tool by hand or with a rotating tool like a cordless
DO be careful while using spinning tools
DO ensure the tool is clicked into the 3/8” Drive securely before starting
DO use a drill speed in the lower range, 200 RPM is a good speed If using with a cordless drill
DO spin the tool prior to engaging with the pipe
DO run the tool along the pipe and back, staying in one place will give you tram lines, the tool is designed to “plane” the surface.
DO use the tool clockwise or anti clockwise, if you change the direction of rotation the tool can “refresh” it ability to brush the surface
DO Change rotation direction while off the pipe
DO Change the File card if it becomes clogged or worn down, spare file cards are available

DO NOTs

[These Do Not’s are not critical but will help the tool to work properly, more safely giving you extending life and better results]

DO NOT push the tool onto the pipe without first rotating the tool
DO NOT pull the tool off the pipe if it is not rotating
DO NOT expect the tool to be a perfect paint removal tool. It will remove some paint but it is not designed to remove paint. Maybe use some emery cloth to start the paint removal process of even heat up the paint before you try to use the Monument Autobrush
DO NOT change the rotation direction while on the pipe
DO NOT keep the tool in one position on the pipe, move it along the pipe back and forth to avoid tramlines
