Snap-on TE50LAC Torqometer, U.S. Light Signal Dial Torque Wrench, 600 in-lb, 3/8″ Drive, with Chart

Description

Air conditioner and refrigeration plants tighten the same joints hundreds of times a shift. For example, think of compressor mounts, valve bonnets and service port caps. The Snap-on TE50LAC Torqometer suits that rhythm, because a lamp flashes when the operator reaches the target. It is a U.S.-reading Light Signal dial wrench with a 3/8-inch drive, and Lost in HCM lists it with a chart.

A signal for repeat work

On a long shift, eyes tire, so a fine dial mark gets harder to read. With the TE50LAC, the operator sets a target and pulls until the light comes on. Then the dial still shows the real value if a lead hand wants to check it. As a result, the tool fits steady, repeated tightening better than a plain dial does.

Snap-on TE50LAC Torqometer data

Also, these figures come from the US Reading dial table in Snap-on’s CAT1500i catalog. That page also says certificate of calibration models carry a C suffix. So the TE50LAC is the C form of the TE50LA.

HVAC tasks that fit a 600 in-lb dial

• Compressor and fan motor mounting bolts.
• Valve bonnet and service valve caps on outdoor units.
• Bracket and panel bolts on chillers and air handlers.
• Spot checks on joints after a leak or noise complaint.

Snap-on’s standard grade holds within 2% of reading from 20% of full scale to full scale. On this dial, the band starts at 120 in-lb. Therefore use the TE50LAC for targets between 120 and 600 in-lb, or roughly 14 to 68 N·m. For small screws, however, choose a lighter tool.

Care on a busy line

Snap-on fits its dial wrenches with heat-treated guards that shield the crystal. Even so, hang the wrench on a rack between jobs rather than dropping it on a bench. Also test the lamp at the start of each shift, and pull smoothly through the target. Finally, return the Snap-on TE50LAC Torqometer to its PB9 case at night, and never use it to break a joint loose.

HVAC line FAQ

Is there a foot-pound version of this size?

Yes. Snap-on lists the TE50FLA light signal wrench, which reads to 50 ft-lb on a 3/8-inch drive.

Can the TE50LAC tighten flare nuts?

It can measure them if your flare spec falls in its band and you use the right crowfoot or socket. Follow the torque your unit maker sets.

What does the chart in the name cover?

Lost in HCM’s listing gives no detail. Since the catalog links the C suffix to a certificate, confirm the paperwork with Lost in HCM.
