Metal Tapered Tube Plugs

Projectile’s Metal Tapered Tube Plugs are designed as a permanent style heat exchanger tube plug. This two piece tube plug comes with a tapered pin and a matching collar to create a total seal. Our Pin and Collar Metal Tube Plugs are designed to seal in high temperature applications and isolate leaking tubes from the rest of the system. They are also designed to be used in tube sheets where a tube sample has been removed. Pin and Collar Metal Tube Plugs can be machined for custom sized tubes and are available in stainless steel, brass, and bronze. Projectile can also manufacture these plugs out of special materials upon request.

Recommended Applications for Metal Tapered Tube Plugs

Application	Typical Location	Why It Matters
Tube Leaks	Condensers & heat exchangers in power plants, chemical plants, and industrial cooling systems	Provides a permanent, high-strength seal to prevent leaks and maintain system efficiency
High-Temperature or High-Pressure Systems	High-capacity heat exchangers, and process loops	Metal construction withstands extreme pressure and temperatures where soft plugs are not suitable
Corrosion-Resistant Sealing	Stainless steel, brass, or bronze-lined tubes	Ensures long-lasting protection in aggressive chemical or marine environments
Permanent Tube Isolation	Systems requiring long-term repairs or phased maintenance	Eliminates the need for temporary solutions or repeated interventions, reducing downtime

Metal tapered tube plugs are engineered for permanent sealing in heat exchanger and condenser applications. Their tapered design allows for a secure, tight fit that ensures reliability and long-term durability even under challenging operating conditions.

Industrial Uses for Metal Tapered Tube Plugs

Metal tapered tube plugs are widely used in industries where safety, reliability, and high-performance sealing are essential. In power generation, they permanently seal leaking condenser tubes, preserving system efficiency and preventing costly downtime. Chemical and petrochemical facilities rely on their robust metal construction to withstand aggressive process fluids while maintaining leak-free operation.

Nuclear power plants also utilize metal tapered plugs for critical heat exchanger maintenance, where precision and durability are non-negotiable. In marine and water treatment applications, these plugs protect systems from corrosion while providing long-term reliability. Across these industries, metal tapered tube plugs offer a dependable solution for permanent tube isolation, ensuring operational continuity and long-term protection.
