About Milton Industries
Milton Industries is a family-owned pneumatic accessories manufacturer founded in 1943 and headquartered in Chicago, Illinois. Over more than eight decades the company has grown from a small family business into a catalog of more than 1,400 SKUs, and it is credited with inventing several now-industry-standard pneumatic products, including the M-Style "I/M" KWIK Change quick-connect coupler and plug still found in shops today. Its product range spans tire gauges and inflators, air couplers and plugs, blow guns, hose reels, filter-regulator-lubricator (FRL) units, and grease guns, sold to automotive, fleet maintenance, construction, and manufacturing customers.
On RevRated, Milton's S-920 Pencil Tire Pressure Gauge is independently featured in our tire pressure gauge testing. Machined from plated brass and marked Made in USA, it pairs a built-in deflator valve with an integrated tread depth gauge, giving glovebox users both a pressure check and a tread check in one pocket-sized tool. Milton marks its Made-in-USA products clearly across its catalog rather than claiming blanket domestic manufacturing, and that is consistent with what we found when we tested the S-920 itself.

Milton S-920 Pencil Tire Pressure Gauge with Tread Depth Gauge
Machined from plated brass, it holds substantially tighter tolerances than imported pencil gauges at the same price, and a built-in deflator valve lets you bleed pressure in controlled increments without removing the gauge, making adjustment a one-handed task. Pocket-sized at under an ounce, it adds an integrated tread depth gauge reading in 1/16-inch increments off the opposite end and a dual PSI-kPa scale for referencing European spec stickers. In our testing it's one of our top picks for a glovebox backup with nothing electronic to fail or corrode, backed by more than 1,700 reviews at a 4.6-star average.
