Pipe thread ring gauge G 3/8" — right-hand Whitworth, hardened gauge steel (Metav IndustryLine)

The pipe thread ring gauge G 3/8" is a precision control gauge for checking right-hand Whitworth pipe threads to DIN ISO 228, suited to workshop and production inspection tasks

• Precision ring gauge G 3/8" right-hand Whitworth
• Hardened gauge steel, tolerance class A
• Conforms to DIN ISO 228 for parallel pipe threads
• Compact, hand-held verification tool

Ensuring correct thread form at first check

A compact ring gauge such as this offers fast, repeatable verification of parallel pipe threads. Manufactured from hardened gauge steel, the item gives stable contact geometry so that checks remain consistent across repeated use; this reduces the need for time‑consuming rework. The combination of material stiffness and a defined tolerance class A provides a clear, objective basis for go/no‑go decisions during incoming inspection or final assembly, improving production throughput and reducing scrap.

Robust construction for routine inspection

Built to withstand frequent handling, the gauge’s hardened construction keeps the measuring surfaces resistant to wear, which preserves precision over many cycles. The ring form suits inline checks and fixture verification, enabling quick conformity assessments without elaborate fixturing. The physical mass of 0.103 kg and compact format make it simple to position by hand or in a light inspection jig, while its defined pitch: 19 and Whitworth thread form ensure compatibility with the relevant pipe fittings and couplings used in mechanical and hydraulic assemblies.

Standards and traceability for quality systems

Conformance to DIN ISO 228 indicates that the thread profile and clearance match established parallel pipe thread standards, which supports documented quality routines and audit trails. The unit’s tolerance class A facilitates classification within a quality plan and helps maintain consistent acceptance criteria across operators. Where calibration is required by the quality system, the gauge’s stable geometry simplifies periodic checks and preserves measurement integrity for documentation and internal audits.
