Ingersoll-Rand 170PG Needle Scaler

The Ingersoll-Rand 170PG is a pneumatic needle scaler built for industrial-duty surface preparation. It uses a 1-5/8 in. stroke at 3,000 blows per minute to remove rust, scale and coatings. The tool requires 90 psi and delivers 5.5 CFM at full load. It includes 19 needles measuring 7 in. each.

Upgrade from manual hand tools

This scaler replaces hand chisels and wire brushes when cleaning large steel structures or welded seams. The jump is worth it when the work volume justifies compressed-air infrastructure and the operator can maintain a 5/16 in. minimum hose size. It accepts manufacturer numbers 1376 and 1377 for needle replacements.

Bayonet housing lock and lever throttle

Installation consists of connecting a 1/4 in. NPT air inlet to a regulated 90 psi supply with adequate flow. The bayonet lock secures the needle bundle quickly, but misalignment can cause uneven wear. Operators must verify hose diameter and pressure before extended use to avoid performance drop-off.

Questions about this item

What air inlet size and hose diameter does the 170PG needle scaler require?

The tool uses a 1/4 in NPT air inlet and needs a minimum 5/16 in hose for proper airflow.

How do you secure the needle cartridge on the 170PG, and what step is often missed?

The housing uses a bayonet lock; align the lugs, push in, then twist until it clicks — skipping the twist leaves the cartridge loose.

When should the 19 included 7 in needles be replaced on the 170PG?

Replace needles when tips become blunt or bent, as worn needles reduce scaling speed and increase vibration.
