Pipe and piping fittings

Hex-head plug

Isolation or routing using a tapered or cylindrical closure element

Specialist selection guide

What should be reviewed before selecting this product?

Hex-head plug belongs to the High-pressure forged fittings family. Technical selection must start from actual service conditions, followed by verification of dimensions, pressure-temperature duty, material, connection, construction standard, testing and manufacturer documentation against the project piping class.

Technical selection path

  1. 1

    Extract class 2000 to 9000 from the project specification and verify it against the manufacturer proposal

  2. 2

    Extract end type from the project specification and verify it against the manufacturer proposal

  3. 3

    Extract thread form from the project specification and verify it against the manufacturer proposal

  4. 4

    Extract forging grade from the project specification and verify it against the manufacturer proposal

  5. 5

    Extract size and reduction from the project specification and verify it against the manufacturer proposal

  6. 6

    Extract material documentation from the project specification and verify it against the manufacturer proposal

Key strengths

  • Selection within the established High-pressure forged fittings family
  • Compatibility review across project materials and connections
  • Structured technical comparison before final enquiry

Selection limitations

  • A trade name or product name alone does not define the technical specification
  • Pressure-temperature limits depend on material, design and standard edition
  • Substitution requires dimensional, functional and documentation verification

Typical applications

Where can this option be considered?

  • Evaluation for Oil and gas projects subject to service-condition approval
  • Evaluation for Refining projects subject to service-condition approval
  • Evaluation for Petrochemical projects subject to service-condition approval

Reference standards

A standard does not replace the project specification

Common technical questions

Concise answers before enquiry

What information is required to enquire about Hex-head plug?

At minimum provide class 2000 to 9000, end type, thread form, forging grade, size and reduction and fluid conditions. Final documentation requirements follow the project specification.

Are two Hex-head plug products with the same name interchangeable?

No. Installation dimensions, pressure-temperature rating, wetted materials, connection, test method and material certification must be checked independently.

Primary purpose

Isolation or routing using a tapered or cylindrical closure element

Best suited to

Fast operation, multi-port duties or particle-laden fluids with suitable design

Selection watchpoint

Lubrication, torque, port arrangement and seat compatibility
