Detailed Information:

RatnaExports.com manufactures, and supplies tapered threaded plugs, sealing plugs, threaded plugs, NPT pipe threads, Taper Pipe Threads, Sealing Plugs, Speedometer Shafts, Speedometer Counter Shafts, Hex Head Plugs, and our setup is available to customers worldwide.

Tapered Plugs are commonly used as plugs or caps to seal openings to prevent dirt, dust, or moisture from intruding, and can also be used as caps for the same reason. It is exceptionally high visibility and durable and has been used by factories worldwide for many years. It is straightforward to install this Tapered Plug. Simply fit them by hand, and they are fitted with a flange to ensure till stay visible in the tube.

We offer a standard stock range of Tapered Plugs available for next-day delivery, and we can also assist you with any custom queries regarding this product. It is well known that tapered plugs and caps are commonly used in various engineering sectors, such as automotive, pipe fabrication, oil and gas, valve manufacturing, and packaging, and providing protection. Our pipe caps are primarily used for typical end capping solutions, but this universally designed tapered plug can also be used as a protective cap. We can manufacture the plugs for you with vent holes if you prefer. Due to the tapered design, the plugs will fit various sizes since they are tapered from bottom to top. Therefore, the plugs can be used to plug multiple inside diameters or to cap multiple outer diameters due to their variable dimensions from bottom to top. Since the low-density polyethylene material is durable and protects against damage, dirt, moisture, and corrosion, it is an excellent choice for storage, shipping, and general protection.

Product Uses

A tapered plug is an excellent option for various holes and ports that are easy to fit. It is made from LDPE and is available in a standard red color. This product is widely used in manufacturing, packaging of finished products for distribution to the customer, and many other industries. They are tapered for a wide range of uses and can be pushed into openings for use as plugs or turned over and placed over tubes or ports for use as caps. Keeping the plug from going in too far and making removal easier is accomplished by the Flange. 


Types Of Tapered Plugs

  • Tapered Plugs

These rubber plugs are often laboratory stoppers and have good impact and abrasion resistance. They’re tapered to fit a range of hole diameters.

  • Hollow Tapered Plugs

 The hollow construction allows these plugs to compress for a snug fit in threaded and unthreaded holes of varying diameters.

  • Hollow Tapered Plug Assortments

 Keep hollow tapered plugs of various sizes on hand to solve whatever problems arise. The hollow construction allows these plugs to compress for a snug fit in threaded and unthreaded holes of varying diameters.

  • Expandable Tapered Plugs

Place a plug into an opening and tighten the wing nut—the sides expand to seal holes in varying diameters.

  • Miniature Tapered Plugs

This tiny plug fits snugly into small openings but can be easily removed using the flange. Their tapered design fits a range of hole diameters.

  • Corks

Lightweight and moisture resistant, these plugs are laboratory-grade 100% natural cork. They’re tapered to fit a range of hole diameters.

  • Pull-Ring Tapered Plugs

Pull the two built-in rings to remove these plugs quickly. All are tapered to fit a range of hole diameters.

  • Tamper-Evident Tapered Plugs

Often used on gas cylinders, these plugs cinch and lock tightly around valve heads to block the ports—they must be cut off, making it clear if the cylinder has been tampered with. The plugs are tapered to fit a range of hole diameters.

  • High-Temperature Tapered Plugs

Suitable for electroplating, paint baking, and powder-coating applications, these plugs withstand temperatures up to 570° F. All are tapered to fit a range of hole diameters.

  • Hollow High-Temperature

The hollow construction allows these plugs to compress for a snug fit in threaded and unthreaded holes of varying diameters. Suitable for electroplating, paint baking, and powder-coating applications, they withstand temperatures up to 450° F.

  • Expandable High-Temperature

Place a plug into an opening and tighten the wing nut—the sides expand to seal holes in varying diameters. Suitable for paint baking and powder-coating applications, these plugs withstand temperatures up to 450° F.

  • Miniature High-Temperature

In addition to being small, they are also easy to remove from small openings. They withstand temperatures up to 470° F, which makes them suitable for electroplating, paint baking, and powder-coating applications. All are tapered to fit a range of hole diameters.

  • Chemical-Resistant Tapered Plugs

These plugs have excellent chemical resistance for masking parts during chemical finishing applications such as plating and anodizing. Their tapered design fits a range of hole diameters.

  • Food Industry Tapered Plugs

The plugs are made from FDA-approved materials. They’re tapered to fit a range of hole diameters.
