Feedthrough Baseplate Coupling Plugs: Precision Blank-Off Solutions for 1″ Vacuum Feedthrough Couplings

Feedthrough Baseplate Coupling Plugs from TFM are specifically designed to securely seal unused 1″ baseplate ports in high-vacuum systems. These components are essential for maintaining vacuum integrity when a feedthrough coupling is not in active use, providing a reliable and clean method for blanking off open ports without disassembly or system modification.

Compatible with vacuum chamber walls ranging from 1/4″ to 1-1/4″ in thickness, these plugs are engineered for straightforward installation and dependable sealing. Whether you’re configuring a new system or retrofitting an existing vacuum platform, coupling plugs ensure operational flexibility while protecting sensitive environments from contamination or leaks.

Key Features of Feedthrough Baseplate Coupling Plugs:

  • Purpose-Built for 1″ Feedthrough Couplings
    Designed to blank off feedthrough ports mounted through standard 1″ baseplate openings.

  • Vacuum-Compatible Materials
    Available in aluminum for lightweight use or stainless steel for robust, corrosion-resistant applications in high-purity or chemically active environments.

  • Reliable O-Ring Sealing
    Each plug includes a vacuum-rated o-ring, ensuring a leak-tight seal when inserted into the feedthrough coupling, with the o-ring positioned inside the vacuum chamber for optimal sealing performance.

  • Supports Modular Vacuum Design
    Allows you to reserve unused ports for future expansion or reconfiguration without compromising vacuum performance.

  • Tool-Free Installation and Removal
    Designed for easy insertion and extraction, enabling quick maintenance and flexible system control.

Applications:

  • Temporarily sealing unused feedthrough ports in research vacuum chambers

  • Preserving system vacuum integrity during phased upgrades

  • Isolating diagnostic or process ports when not in use

  • Protecting internal chamber environments from ambient air or contamination

  • Modular HV/UHV platform designs with configurable plumbing

TFM also offers feedthrough couplings, NPT-compatible tube fittings, and compression o-ring connectors to support comprehensive vacuum system configuration.

In summary, Feedthrough Baseplate Coupling Plugs are an essential part of vacuum infrastructure, providing high-integrity sealing and modular flexibility. With stainless steel and aluminum options and full o-ring compatibility, they offer a dependable solution for managing open feedthrough ports in critical vacuum environments.

FAQ

Tube fittings are designed for tubes (measured by outside diameter and wall thickness) used in high-pressure and instrumentation applications, whereas pipe fittings are for pipes (identified by nominal pipe size) primarily used in fluid transport.

 

Common valve types include ball valves, gate valves, check valves, butterfly valves, and globe valves. Each serves a specific function—from quick shutoff (ball/gate valves) to flow regulation (globe valves).

 

  • For tubing, measure the outside diameter; for pipes, refer to the nominal pipe size (using conversion charts if needed). Always match the valve or fitting size to your pipe’s dimensions and flow requirements.

  • Frequently used thread types include NPT (National Pipe Tapered), BSP (British Standard Pipe), and UNC, along with slip-fit options that rely on compression or fusion rather than threads.

Interchangeability depends on manufacturer specifications and certification. Always verify compatibility via manufacturer guides or certified interchangeability charts.

 

  • A coupling is a short, straight fitting used to join two pipes or tubes. It provides a secure, leak-tight connection and can sometimes serve to extend or repair piping runs.

Consider valve type, pressure and temperature ratings, material compatibility with your fluid, actuation method (manual or automatic), and maintenance requirements.

 

  • Valves regulate flow by opening, closing, or partially obstructing the pathway. Their mechanisms (such as the rotation of a ball or the linear movement of a gate) determine the speed and precision of flow control.

  • A flange is a flat, circular component used to connect pipes, valves, or other equipment. Bolted together with gaskets, flanges provide a secure, leak-proof joint that facilitates both assembly and maintenance.

  • Manual valves require physical operation via handles or levers, whereas actuated valves use mechanisms—pneumatic, electric, or hydraulic—to open and close automatically or remotely.

  • Issues include leaks caused by improper installation, over-tightening, degraded seals, material incompatibility, and fatigue from repeated cycling. Regular inspection and proper installation practices help mitigate these problems.

Regular maintenance involves periodic inspections, cleaning or replacing worn seals, ensuring proper torque during installation, and adhering to manufacturer guidelines and local plumbing codes to preserve system integrity.
