Services

Everything from a drip to a full rebuild

We work on manual and electronic oil meter guns used for motor oil, ATF, gear lube, and coolant.

SVC-01

Leak repair

Replace worn seals, O-rings, and swivels so the gun stops weeping oil on your bench and your floor.

SVC-02

Full rebuild

Teardown, cleaning, new wear parts, and reassembly for guns that are sticking, dragging, or won't shut off.

SVC-03

Calibration & testing

Every gun is run against a measured volume and adjusted until the readout matches what actually comes out.

SVC-04

Meter replacement

Swap out cracked, fogged, or dead digital and mechanical meters, including preset-quantity meters.

SVC-05

Nozzles & triggers

Rigid and flexible extensions, anti-drip tips, trigger springs, and locks replaced or upgraded.

SVC-06

Shop-wide service

Bring in every gun on your reels at once. We check, tag, and return them as a set to keep your bays running.

How it works

Drop it off, get it back right

  1. Drop off or ship

    Seals, parts, and meters replaced as needed.

  4. Test

    Flow-tested for leaks and checked for accurate readings.

  5. Return

    Back to you with a test ticket showing the result.

Fluids

What runs through the guns we fix

Calibration is checked with the fluid type you use, because thick gear oil and thin ATF don't meter the same way.
