Apex 81648 Flare Nut Wrench 16MM X 18MM Chrome Standard

Product Description

The APEX 81648 is a standard-pattern flare nut wrench sized at 16MM x 18MM, designed for loosening and tightening hex nuts in tight spaces where tubing is present. Built from alloy steel with a full polish chrome finish, this wrench delivers corrosion resistance and long service life in demanding trade environments. At 8.287 inches in length and 0.46 pounds, it is compact enough for confined work areas while providing solid leverage on hex fasteners. HVAC technicians, plumbers, and automotive service professionals reach for flare nut wrenches when working around fuel lines, brake lines, refrigerant tubing, and hydraulic fittings where an open-end wrench risks rounding the nut.

The 81648 fits standard service applications involving hex nuts on tubing connections. The dual-size configuration — 16MM on one end and 18MM on the other — consolidates two common metric sizes into a single tool, reducing the number of wrenches needed on the job. It is well suited for residential and light commercial HVAC work, plumbing rough-in, and general mechanical service wherever metric flare fittings are encountered.

Key Features

• Dual-size ends: 16MM and 18MM on a single wrench
• Standard pattern body for use in conventional access spaces
• Alloy steel construction for strength and durability
• Full polish chrome finish resists corrosion and simplifies cleanup
• 8.287-inch length provides balanced reach and leverage
• Sold individually (each)

Compatibility

Designed for use on metric hex nuts where tubing is present, including refrigerant line fittings, fuel lines, brake lines, and hydraulic connections requiring 16MM or 18MM wrench engagement.

Installation Notes

Flare nut wrenches are typically used by licensed HVAC technicians, plumbers, and mechanical service professionals. Always depressurize or isolate the line before breaking a flare fitting connection. Use the correct size end to avoid rounding the nut, and do not apply extension bars or pipe to increase leverage beyond the wrench design.
