American Thread Identification Kit - Complete Hydraulic Thread Gauge

In this review the American Thread Identification Kit is assessed as a compact, practical toolset for anyone who works with hydraulic fittings and needs fast, reliable identification on the bench or job site. The single biggest reason to buy is the kit's ability to measure both O.D. and I.D. across common fitting types while also providing a thread pitch gauge and taper indicators, which together eliminate guesswork when matching NPT, NPSM, ORFS, JIC, ORB and SAE 45 fittings.

Key Features

• Versatile measurement range: Six plastic cards let the user check O.D. and I.D. for NPT, NPSM, ORFS, JIC, ORB and SAE 45 fittings so a wide variety of hydraulic connections can be identified.
• Comprehensive thread pitch tool: The included TPI gauge covers imperial sizes from 11 to 28 and metric threads of 1mm, 1.5mm and 2mm so most common thread types can be verified quickly.
• Angle measurement capabilities: Four taper pieces measure 37, 45, 12 and 60 degree tapers to confirm seat angle compatibility on fittings and adapters.
• Durable construction: Gauges and tools are made from sturdy materials intended for industrial use, giving confidence that the kit will hold up to frequent shop and field use.
• Easy reference charts: Each card includes clear labels with dash size, nominal size and threads per inch to speed identification and reduce errors during matching.

Who It's For

This kit is aimed at hydraulic technicians, maintenance mechanics and shop owners who regularly deal with a mix of thread standards and need a portable, organized way to identify fittings on the fly. The compact vinyl bag makes it practical for service trucks, shop benches or parts departments where quick identification prevents downtime.

It may be less useful for users who only ever work with a single, known standard and do not need multiple cards or taper gauges; such specialists can consider single-purpose gauges instead. For generalists and those who encounter varied fittings, this kit streamlines diagnosis and ordering.

Pros & Cons

Pros

• Accurate identification across many common hydraulic fittings due to combined O.D./I.D. cards and TPI gauge.
• Includes taper gauges for seat angle checks, reducing mismatches when replacing fittings.
• Neat, portable storage in a vinyl bag keeps tools organized for field use.
• Clear charts and labels make matching sizes quick even for less experienced users.

Cons

• Thread type identification receives mixed feedback from some users, so occasional cross-checking may be needed for uncommon or worn fittings.
• The kit is plastic-based, which while durable, may not replace precision metal gauges for laboratory calibration work.
