Take advantage of a hardened gauge steel construction combined with DIN ISO 228 conformity to ensure repeatable, workshop‑grade inspection of Whitworth pipe threads; purchase the gauge directly via Metav Werkzeuge or request further advice from our consultants.

Pipe thread ring gauge G 1/2 (right‑hand) — Whitworth inspection gauge (Metav IndustryLine)

A pipe thread ring gauge G 1/2 designed for fast verification of right‑hand Whitworth pipe threads in production and quality control environments.

• Hardened gauge steel for robust, repeatable checks
• Conforms to DIN ISO 228 for thread specification
• Right‑hand G 1/2″ for Whitworth pipe thread inspection

Ensure thread conformity quickly and reliably

The ring is made from hardened gauge steel, providing long service life and stable checking characteristics even under frequent use. In practice this means fewer replacements and consistent pass/fail results over time. The G 1/2″ form is suited to standard pipe fittings and the Whitworth profile it verifies is widespread in legacy and specialist installations, so the gauge accelerates inspection throughput while reducing process variation.

Meet standards and reduce rework

Compliance with DIN ISO 228 gives a clear, verifiable basis for acceptance criteria and helps to avoid subjective assessments on the shop floor. The gauge’s tolerance class A ensures strict dimensional limits that support interchangeability and minimise scrap. Using a standardised ring like the M315.404 in routine checks supports traceable quality control and demonstrates due diligence during audits or customer inspections.

Practical benefits for workshop and production use

Weighing approximately 0.22 kg and featuring a 14 pitch, the ring is compact and easy to handle on gauging benches or assembly lines. The compact mass aids quick manual checks without operator fatigue while the hardened construction maintains the mating surface geometry needed for reproducible measurements. As a dedicated inspection tool it simplifies go/no‑go decisions and integrates seamlessly into existing QC routines.
