ASA HV Standard Full Nipples (Grooved Flanges)

ASA HV Standard Full Nipples (Grooved Flanges)

ASA HV Standard Full Nipples (Grooved Flanges): Dual-Grooved Vacuum Nipples for ASA O-Ring Sealing Interfaces

ASA HV Standard Full Nipples (Grooved Flanges) from TFM are designed to deliver robust and leak-tight straight-line connections between ASA-standard components in high-vacuum (HV) systems. Fabricated using 304L stainless steel tubing, these full nipples feature exceptional mechanical strength, corrosion resistance, and vacuum cleanliness.

Each unit is equipped with two rotatable grooved ASA flanges, making them ideal for mating with flat ASA flanges in accordance with sexed ASA sealing standards. The grooves are precisely machined to seat elastomeric o-rings, ensuring secure compression when bolted against flat mating surfaces.

This configuration is perfect for systems built around o-ring sealed ASA flanges, offering both structural continuity and consistent vacuum performance.

Key Features of ASA HV Standard Full Nipples (Grooved Flanges):

  • Dual Grooved ASA Flanges
    Designed for mating with flat ASA flanges using elastomeric o-rings, supporting vacuum operation down to 10⁻⁸ Torr or lower.

  • 304L Stainless Steel Construction
    Provides high corrosion resistance, weldability, and durability under thermal cycling—essential for demanding high-vacuum processes.

  • Rotatable Flanges for Installation Flexibility
    Both grooved flanges are rotatable to simplify alignment and assembly, especially in tight or modular layouts.

  • Straight, Full-Length Spool Design
    Ideal for creating rigid, leak-tight interconnections between ASA-flanged components without directional change.

  • Leak Tested and Vacuum Cleaned
    All ASA HV Standard Full Nipples (Grooved Flanges) are helium leak tested and prepared to vacuum-grade cleanliness.

  • Standard and Custom Options Available
    Available in common ASA sizes (4″, 6″, 8″, 10″, 12″), with customizable tube lengths, wall thicknesses, and flange size combinations upon request.

Applications:

  • Vacuum line extension between grooved-to-flat ASA flange interfaces

  • Interconnection of pumps, chambers, or gauges in ASA-based HV systems

  • O-ring sealed straight-line routing in foreline or exhaust paths

  • Modular vacuum infrastructure in research, semiconductor, or aerospace environments

  • Retrofit or expansion of existing ASA vacuum assemblies

TFM also provides flat ASA flanges, o-rings (FKM, Buna-N), bolt kits, and matching reducer fittings for seamless system integration.

In summary, ASA HV Standard Full Nipples (Grooved Flanges) offer a straightforward and secure solution for extending or linking ASA-standard vacuum components with o-ring sealing. Their robust design, precision fabrication, and compatibility with grooved sealing conventions make them a dependable choice for any HV system requiring structural and vacuum-tight continuity.

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.
