Spi 14-198-6 Telescoping Gage 3.5 to 6 Inch

Product Description

The SPI 14-198-6 is a telescoping gage designed for measuring inside diameters, bores, and slot widths in trade and industrial applications. It spans a measurement range of 3.5 to 6 inches with an overall length of 5.85 inches and a 5-inch handle. The gage is constructed from hardened tool steel for durability under repeated use, and the working faces are TiN coated to resist wear and extend service life. A satin chrome finish on the body reduces glare during use. This tool is typically used by machinists, pipefitters, plumbers, and HVAC technicians who need accurate inside measurements transferred to a micrometer or caliper for reading.

This telescoping gage suits residential and commercial service work where inside bore measurements are required. Common applications include checking pipe bore diameters, valve seats, cylinder bores, and housing bores during installation or inspection. The 3.5 to 6 inch range covers a wide variety of standard bore sizes encountered in mechanical and plumbing trade work. It is suited for bench use and field service where a quick, reliable transfer measurement is needed before final verification with a precision measuring instrument.

Key Features

• Measurement range of 3.5 to 6 inches for inside diameter and bore applications
• Overall length of 5.85 inches with a 5-inch handle for controlled reach
• Hardened tool steel construction for long-term durability
• TiN coated working faces for reduced wear on contact surfaces
• Satin chrome finish minimizes glare and corrosion on the body

Compatibility

Designed as a general-purpose telescoping gage for inside measurement applications across mechanical, plumbing, and HVAC trade work where bore sizes fall within the 3.5 to 6 inch range.

Installation Notes

This gage is a hand measurement tool and does not require installation. Compress the telescoping contact points before inserting into the bore, allow them to expand against the bore wall, then lock the knurled knob before withdrawing and transferring the measurement to a micrometer or outside caliper. Keep contact faces clean and free of debris to maintain measurement accuracy. Inspect TiN coating periodically for wear that could affect reading consistency.
