Pipe Thread Go Gauge G 1/4 — Whitworth, right-hand (Metav IndustryLine)

The Pipe Thread Go Gauge G 1/4 Whitworth (right-hand) is a hardened inspection ring designed for fast, repeatable acceptance testing of parallel pipe threads in production and incoming inspection.

• Hardened gauge steel for long service life
• Conforms to DIN ISO 228 for pipe threads
• Tolerance class A precision

Faster decision-making at the inspection bench

The Go gauge checks whether a threaded component meets the acceptance limit without time‑consuming measurements. By verifying that a G 1/4 Whitworth thread engages freely within the gauge, the inspection process is reduced to a clear pass/fail decision, minimising line stoppages and rework. The hardened construction ensures consistent seat and maintains the dimensional reference through many inspection cycles, so acceptance decisions remain reliable over time.

Durable construction that reduces lifetime costs

Manufactured from hardened gauge steel, the measuring ring offers high wear resistance in routine shop use. The robust material and heat treatment keep the functional surfaces stable, which reduces the need for frequent replacement and preserves calibration intervals. For production environments where traceable checks are performed repeatedly, this construction delivers lower total cost of ownership through extended service life and fewer unplanned tool changes.

Standards-based inspection for regulatory confidence

Designed to the DIN ISO 228 standard, the ring provides a documented basis for conformity assessment of parallel pipe threads. The tolerance class A rating indicates tight manufacturing limits for use in precision acceptance testing and formal quality records. Where auditability and traceable acceptance criteria are required, the standard conformity supports complaint handling and supplier control without additional interpretation.

Practical fit in assembly and quality workflows

The compact ring format is simple to integrate at incoming inspection, final assembly checks or line-side verification stations. The right‑hand Whitworth thread form and nominal designation G 1/4 are clearly marked on the gauge to avoid misapplication, and the light mass supports easy handling and rapid cycling between parts. This makes the gauge suitable for both workshop benches and production lines where repeatable, operator‑friendly checks are needed.

FAQ

What does the Go ring gauge check on pipe threads?
The Go ring gauge verifies that the external pipe thread accepts the gauge without interference; the Metav IndustryLine Go gauge G 1/4 (SKU M315.322) confirms that the thread is within the acceptance envelope specified by DIN ISO 228.

Is the ring suitable for right‑hand and left‑hand threads?
This specific ring is for right‑hand Whitworth pipe threads in the G 1/4 size; left‑hand variants require the corresponding left‑hand gauge.

How does tolerance class A affect inspection decisions?
Tolerance class A indicates a tighter acceptance limit; using the Metav IndustryLine gauge with this class ensures higher precision during acceptance testing and helps maintain consistent quality standards.
