Low-Pressure Galvanized Iron and Steel Threaded Pipe and Pipe Fittings

510 Products

LILY Bearing stocks low-pressure galvanized iron and steel threaded pipe nipples, pipe, and flanges — the zinc-coated counterpart to our uncoated steel threaded line, including nipples made specifically for joining galvanized steel to a dissimilar metal.

Category Product Type Material Watch Out For
Standard-Wall Galvanized Steel Threaded Pipe Nipples and Pipe Nipples & pipe Galvanized steel The base, general-purpose option — zinc coating protects against corrosion but isn't rated for high pressure or high temperature
Standard-Wall Galvanized Steel Threaded Pipe Nipples and Pipe with Sealant Nipples & pipe Galvanized steel Thread sealant is factory-applied — saves an installation step, but confirm it's compatible with your service temperature
Standard-Wall Galvanized Steel Threaded Pipe Nipple and Pipe Assortments Multi-size kits Galvanized steel Useful for stocking a range of sizes without ordering each one separately — check the kit contents against what you actually need
Standard-Wall Galvanized Steel Pipe Nipples and Pipe for Joining Dissimilar Metals Nipples & pipe Galvanized steel Built to reduce galvanic corrosion when connecting galvanized steel directly to a different metal — not a substitute for a regular nipple in an all-steel run
Low-Pressure Galvanized Steel Threaded Pipe Flanges Flanges Galvanized steel Standard bolt pattern for moderate-duty piping — not for high-pressure service
Low-Pressure Galvanized Iron and Steel Threaded Pipe Fittings with Sealant Fittings (elbows, tees, couplings) Galvanized iron & steel Broader than the nipple-and-pipe sealant line above — covers shaped fittings, not just straight lengths

 

Joining Galvanized Steel to a Different Metal

Connecting galvanized steel directly to a dissimilar metal — copper or stainless steel, for example — can set up galvanic corrosion at the joint over time. Our dissimilar-metal nipples are built to reduce that risk, so it's worth using them anywhere your run transitions between galvanized steel and another metal, rather than defaulting to a standard nipple.

Frequently Asked Questions

Why do I need a special nipple to join galvanized steel to another metal?

When two dissimilar metals are in direct contact in the presence of moisture, one metal corrodes faster than it would on its own — a process called galvanic corrosion. A dissimilar-metal nipple is built to reduce that risk at the transition point, which a standard galvanized nipple isn't designed to do.

What's the difference between the two "with sealant" categories?

The nipple-and-pipe sealant category covers only straight nipples and pipe lengths. The broader "Pipe Fittings with Sealant" category covers shaped fittings — elbows, tees, and couplings — that also come with sealant factory-applied.

Why choose galvanized steel over plain (uncoated) steel fittings?

The zinc coating on galvanized steel protects the base metal from rust and corrosion, which makes it a common choice for outdoor piping, water lines, and other applications exposed to moisture that uncoated steel would need extra protection to handle.

Why choose a nipple with sealant pre-applied?

Thread sealant is normally applied by hand during installation. A pre-applied version saves that step and reduces the chance of an under- or over-applied seal, which is useful for high-volume installs or field technicians who need a consistent result.
