Thread ring gauge G 1 3/4 Go, Whitworth — hardened gauge steel, right-hand (Metav IndustryLine)

A Thread ring gauge G 1 3/4 Go Whitworth for repeatable acceptance testing of right-hand pipe threads in workshop and production environments.

• Hardened gauge steel construction
• Conforms to DIN ISO 228
• Go ring for G 1 3/4 Whitworth pipe thread
• Tolerance class A precision

Repeatable, standards-based acceptance testing

The Go ring design provides a quick go/no-go decision for external Whitworth pipe threads, allowing inspection tasks to be completed in seconds without complex setups. Built to the DIN ISO 228 pipe-thread standard and specified as G 1 3/4, the gauge checks whether an external thread meets the maximum material boundary defined by the standard. With Tolerance class A, the gauge supports tight conformity requirements typical for industrial assembly and hydraulic connections, helping to reduce rework and secure assembly reliability in serial production.

Durable construction for long service life

Manufactured from hardened gauge steel, this inspection ring resists wear and maintains dimensional stability under repeated use, preserving measurement certainty over many inspection cycles. The right-hand orientation matches conventional pipe-thread production, while the compact mass (approx. 0.9 kg) makes handling straightforward on the shop floor. The robust material choice reduces the frequency of replacement, contributing to lower operating costs and predictable quality control intervals.

Practical integration into quality workflows

A Go ring gauge integrates naturally into incoming inspection, in-process checks and final acceptance routines: the physical pass/fail result speeds throughput and simplifies documentation. The clear mechanical function of the gauge complements digital quality systems by delivering an immediate decision at the machine or inspection bench; when traceability is required, the ring can be recorded as part of a gauge inventory or quality plan. For production environments seeking a pragmatic balance of speed and precision, this ring gauge supports consistent conformance to specification and faster line acceptance.

FAQ

What does the "Go" designation mean for this ring gauge?
The "Go" designation indicates the ring is a pass gauge: the external thread must enter the Go ring gauge G 1 3/4 Go Whitworth to be accepted under the specified limits.

Is this ring suitable for production use on workshop benches?
Yes. The Metav IndustryLine Go ring gauge is made of hardened gauge steel and designed for frequent acceptance checks in workshop and production environments.

How does the gauge relate to DIN ISO 228?
The gauge is produced to conform with DIN ISO 228, ensuring the thread form and limiting dimensions align with the corresponding Whitworth pipe-thread specification.

How should the ring gauge be cared for to maintain accuracy?
Store the gauge dry and clean after use; avoid impacts and severe contamination. Regular visual checks for wear are recommended for the Metav IndustryLine ring gauge M315.331.

Can the gauge check both handedness and pitch?
The ring is right-hand and specified with a Pitch: 11, so it is intended for right-hand Whitworth pipe threads matching that pitch.
