API 6A Ring Gaskets for Oil and Gas

Precision-Machined Metal Seals for Extreme Pressure Applications


API 6A Ring Gaskets Manufacturing with Align MFG
Overview

API 6A Ring Gaskets Component Manufacturing

API 6A ring gaskets form the backbone of high-pressure sealing in upstream oil and gas operations. Used across wellhead assemblies, blowout preventers (BOPs), and manifold systems, these metal-to-metal gaskets ensure zero-leak performance under extreme temperature and pressure cycles.

Align Manufacturing produces API 6A-compliant ring gaskets in R, RX, and BX profiles, built from NACE-compliant materials and machined with exacting dimensional control. Our global production model, spanning facilities in India, Vietnam, and Thailand, delivers parts that meet Western quality expectations without the unpredictability often associated with offshore sourcing.

Key Features

Ring Gasket Types We Produce

Type Applications Pressure Rating
R Type Standard flanges, moderate HPHT service Up to 5,000 psi
RX Type High-pressure flanges, BOPs, wellheads Up to 15,000 psi
BX Type API 6A Type BX flanges, extreme service Up to 20,000 psi

Available in oval or octagonal cross-sections based on your application requirements.


Sealing Solutions You Can Count On

At Align, we know that even the smallest sealing component can cause massive operational issues if it fails. That’s why every API 6A ring gasket we machine undergoes rigorous quality control processes:

  • Certified material sourcing for sour gas and HPHT service

  • Batch-level and part-level traceability

  • Dimensional and surface finish verification using calibrated inspection tools

  • Packaging and labeling to prevent surface damage in transit

Applications

Applications for API 6A Ring Gaskets

 

Align’s API 6A ring gaskets are built for:

  • Wellhead Equipment (Casing Heads, Tubing Heads, Spools)

  • Blowout Preventer (BOP) Systems

  • Frac Trees and Isolation Assemblies

  • Choke and Kill Manifolds

  • Subsea Production Trees

  • Pressure Control Systems

Specifications

Manufacturing Capabilities Snapshot

Capability Details

Ring Gaskets in Manifolds and Flanged Connections

In addition to standalone wellhead and BOP applications, API 6A ring gaskets play a critical role in the reliable performance of manifolds and flanged flowline connections.

Frac manifolds, choke manifolds, and flowback skids often rely on properly specified BX or RX gaskets to maintain pressure integrity across high-load cycles. Misalignment or improper material selection can lead to leaks, downtime, and safety risks — which is why Align offers expert support in material selection and profile specification to match your system needs.
