When to use dielectric fittings?
Dielectric fittings are used when connecting dissimilar metals in plumbing or electrical applications to prevent galvanic corrosion. They are essential in systems where copper and steel, for example, are joined, as the interaction can lead to corrosion of one of the metals. Additionally, dielectric fittings help maintain electrical insulation between conductive materials, ensuring safety and system integrity. It's advisable to use them in areas exposed to moisture or when long-term reliability is a concern.
Can you do brass to galvanized conduit connection?
Can you do it - yes. SHOULD you do it - NO. Because brass and galvanized conduit have different electrochemical potentials (go talk to a chemistry teacher if you need an explanation of electrochemical potential) if you place them in direct contact with each other, you will set up a galvanic differential and promote corrosion. If you must connect brass and galvanized conduit, you should use a connector between the two that will isolate them electrically from each other. In essence, you are "insulating" them from each other so that you don't get an electric current between them to promote corrosion. There are special fittings, I believe they are referred to as "dielectric fittings" that are designed to provide this insulation and avoid the problem of galvanic corrosion. The more corrosive the liquid you have in the pipes, the more important it is to use these special fittings. Hard or salty water can particularly problematic.
How can you prevent galvanic corrosion between 304 stainless steel piping and galvanized saddle tap fittings?
Completely isolate the electrical circuit - so use some insulation such as PVC to ensure the metals are not in contact - but the above situation should not be allowed in the first place - very poor design indeed.
What is the difference between Wrought and forged Fittings?
The main difference between wrought and forged fittings is strength. Forged fittings are tougher than wrought fittings as they begin as a casting which is then forged which adds to its durability.
What happens when dielectric breakdown occurs?
The dielectric,usually the insulator between the plates of a capacitor, can be overstressed by the application of too high voltages applied to the capacitor plates. The dielectric breaks down and a current flows between the plates until,either they are discharged, or an equilibrium is reached,below the working voltage of the capacitor. If the dielectric is damaged in this process he capacitor must be replaced. Some dielectric material self heal and can recover from an over voltage.
What are the differences between galvanized and stainless steel in terms of their durability and resistance to corrosion?
Galvanized steel is coated with a layer of zinc to protect against corrosion, making it durable and resistant to rust. Stainless steel, on the other hand, is inherently corrosion-resistant due to its composition of chromium and nickel. Stainless steel is generally more durable and has a higher resistance to corrosion compared to galvanized steel.
What are the differences between galvanized and stainless steel cable in terms of durability and corrosion resistance?
Galvanized steel cable is coated with a layer of zinc to protect against corrosion, making it more durable and resistant to rust compared to stainless steel cable. Stainless steel cable, on the other hand, is inherently corrosion-resistant due to its composition, but may not be as durable as galvanized steel in certain environments.
Do you need dielectric fitting between black iron pipe and stainless steel?
Yes, need one between the two dissimilar metals.

What dielectric material is to be used between aluminium cladding and stainless steel cladding at contact surface?
A common dielectric material used between aluminum and stainless steel cladding is polyethylene tape or a polyester film. These materials help prevent galvanic corrosion by acting as a barrier between the two dissimilar metals. It is essential to choose a material with good insulating properties to effectively isolate the aluminum and stainless steel.
What are the differences between PEX cinch and crimp fittings, and which one is more suitable for my plumbing project?
PEX cinch fittings use a stainless steel ring to secure the connection, while crimp fittings use a copper ring. Cinch fittings are easier to install and require less force, making them more suitable for DIY projects. Crimp fittings are more durable and have a longer lifespan, making them better for professional installations or high-pressure systems. Consider your skill level and project requirements when choosing between the two.
What is the difference between 18 gauge and 22 gauge stainless steel?
The difference between 18 gauge and 22 gauge stainless steel is the thickness. The 18 gauge is 0.050" thick, and the 22 gauge is 0.031" thick. A link is provided below to an article with a list of the conversions. You'll note that the cited thickness for the gauges of stainless do not apply to galvanized steel, aluminum, zinc, brass or other metals.
What are the differences between PEX crimp and cinch fittings for plumbing applications?
PEX crimp fittings require a special tool to compress a metal ring around the PEX tubing, creating a secure connection. Cinch fittings use a stainless steel ring and a cinch tool to secure the tubing in place. Crimp fittings are more commonly used and provide a stronger connection, while cinch fittings are easier to install but may not be as reliable in the long term.
Can copper and galvanized pipes be used on the same fitting?
Yes and no. Pipes are pipes and many houses have both copper and galvinized. But copper and galvinized pipe must never come into direct contact with each other. You have to put what's called a dielectric fitting (available at your local hardware store) in between them. The problem is that without a dielectric fitting you'll get what's called electrolysis. Electrolysis eats holes in your pipes. Like I said, just put in a dielectric fitting. No sweat.
