About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

High-Pressure Brass and Bronze Threaded Pipe Fittings

High pressures are no problem for these heavy-duty fittings. They are brass for good corrosion resistance.

Miniature Low-Pressure Brass and Bronze Threaded Pipe Fittings

Less than an inch in length, these miniature fittings work well in low-pressure pipe lines that are tight on space. They are brass, which has good corrosion resistance.

Slotted External-Hex-Drive Plugs with Gasket

Male

UN/UNF (SAE Straight) Thread—Also known as O-ring boss threads.

Nickel-Plated 360 Brass—Nickel-plated brass pipe provides better corrosion resistance than unplated brass.

Fixture Plate Plugs

Fill unused holes on fixture plates and columns to keep chips and shavings from clogging or damaging them. These plugs are easy to install and remove, so you can switch them to a different hole when you need to change setups.

Screw-In Plugs for Threaded Holes


Black-Oxide Steel	Aluminum	Plastic

Install screw-in plugs into threaded holes with a screwdriver. They have a slotted drive that resists chip buildup.

Black-Oxide Steel—Black-oxide steel plugs are the most durable, so they’re good for repeated use in demanding applications. The black oxide coating provides mild corrosion resistance.

Aluminum—Aluminum plugs are more corrosion resistant than steel plugs—they’re also gentler on steel threads.

Plastic—Plastic plugs are lightweight and economical.

Breather Vents


Style G	Style F

Protect against excess vacuum and pressure in cylinders, gear boxes, enclosures, manifolds, and tanks. You can also use these breather vents to block debris from entering equipment.

Style G—Style G has a slotted drive for installation with a screwdriver.

Thread-Locking Threaded Inserts

With Loctite® adhesive already on the threads, these inserts won’t back out or vibrate loose. The adhesive reaches full strength after 72 hours. Unlike helical inserts, you can install them with a standard drill and tap. However, thread-locking inserts are difficult to remove and reuse.

After drilling and tapping your hole, install inserts with a wrench or an installation bit. To use a wrench, thread an insert and two hex nuts onto a bolt. Then, grip and turn the top nut to drive into the hole. For slotted inserts, you can drive with a slotted screwdriver instead.

Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.

Thin Wall—Use these inserts near the edge of workpieces or wherever you only have space for a small hole. They're also lighter than standard and extra-thick wall inserts for applications with strict weight limits.

Extra-Thick Wall—Stronger than standard- and thin-wall inserts, use them to reduce the size of tapped holes or replace threads that have been drilled out.

Black Phosphate-Coated Steel—These inserts resist occasional moisture.

18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these inserts won't degrade when exposed to harsh weather, salt water, and most chemicals.

Thread-Locking Threaded Insert Assortments

These assortments include various sizes of thread-locking inserts, which won’t back out or loosen from vibration. Also known as E-Z Lok, they come with Loctite® adhesive already applied, and the adhesive reaches full strength after 72 hours. After drilling and tapping your hole, install inserts with a wrench or use an installation bit (not included). To use a wrench, thread an insert and two hex nuts onto a bolt. Then, grip and turn the top nut to drive into the hole.

Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.

Black Phosphate-Coated Steel—These inserts resist occasional moisture.

18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

Tapping Threaded Inserts for Hardwood

The sharp threads on these inserts cut into hardwood for a secure hold. They install in one step, so they’re ideal for quickly creating a lot of threaded connections in wooden fixtures and panels. All you need is a drill and an installation bit. Also known as knife-thread inserts.

Brass—Conductive and nonmagnetic, these inserts are useful for electrical applications. They resist moisture but aren't as strong as steel inserts.

18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.
