G 7/8" Pipe Thread Go Ring Gauge Whitworth Right-Hand Hardened Gauge Steel, DIN ISO 228 - Metav IndustryLine

Take advantage of a robust inspection tool that combines hardened gauge steel construction with nominal compliance to DIN ISO 228 and a clear tolerance class A designation; note that this item is supplied as an Ausschuss (non‑conforming) article and is therefore suited to non‑critical verification, training or as a spare. Order or request advice directly via Metav Werkzeuge for an informed purchase.

Pipe thread ring gauge G 7/8 — right‑hand, hardened gauge steel (Metav IndustryLine)

A pipe thread ring gauge G 7/8 designed for quick verification of parallel pipe threads in workshop and inspection environments; right‑hand thread form with 14 tpi, nominally to DIN ISO 228

• Hardened gauge steel construction
• G 7/8 parallel pipe thread, right‑hand
• Tolerance class A for precise checks

Durable construction for dependable shop verification

Manufactured from hardened gauge steel, this ring gauge delivers mechanical stability and wear resistance that benefits repeated shop‑floor use. The robust material reduces deformation under normal handling and preserves the functional profile for longer intervals, which supports consistent pass/fail checks. As a nominally DIN ISO 228 product, the ring is intended for parallel pipe thread verification; however, this particular unit is marked Ausschuss (non‑conforming), so it is best applied where absolute certification is not mandatory, such as training, process trials or as a cost‑effective spare.

Technical compatibility and practical benefits

With a thread pitch of 14 tpi and a right‑hand thread form, the gauge corresponds to the conventional G‑series dimensions and is compatible with fittings specified to that standard. The tolerance class A designation identifies the intended precision band for gauging operations, enabling straightforward go/no‑go assessments during incoming inspection or routine checks. The compact mass and simple geometry make it easy to handle and to fit into standard inspection workflows, reducing non‑productive time and supporting a predictable quality control routine.

Suitability, limitations and procurement guidance

This unit is offered from the Metav IndustryLine range as an Ausschuss item and therefore supplied as‑is. It is suitable for non‑critical checks, staff training and as a reference for comparative measurements, but it should not replace certified gauges in final inspection of critical assemblies. The lightweight construction (0.3 kg) eases handling and transport between workstations. For applications requiring full conformity or calibration certificates, please consult Metav Werkzeuge to identify a certified alternative or to discuss possible reconditioning options.

FAQ

What is this gauge intended for?
This pipe thread ring gauge M315.407 is intended for verification of G 7/8 parallel pipe threads in workshop and inspection contexts, especially for non‑critical checks, training and process trials.

Is the thread right‑hand or left‑hand?
The ring gauge is a right‑hand thread with a 14 tpi pitch corresponding to the G‑series parallel pipe thread form.

What does Ausschuss mean for this item?
Ausschuss indicates the item is non‑conforming and supplied as‑is; M315.407 is therefore best used where full certification is not required or where the gauge serves as a spare or training tool.

Which material and standard apply to the gauge?
The gauge is made from hardened gauge steel and is designated against DIN ISO 228 with tolerance class A as its nominal specification.

Can this gauge be used for final acceptance testing?
Because M315.407 is supplied as an Ausschuss unit, it is not recommended for final acceptance of critical assemblies; request a certified gauge from Metav Werkzeuge for final inspection tasks.
