Accupro QAP-2 1/8LS Tapping Adapter 1/8 in Ls Pipe Size 2

Product Description

The ACCUPRO QAP-2 1/8LS is a quick-change tapping adapter designed to connect 1/8-inch LS pipe taps to compatible tap holders in a fast, tool-free interface. The adapter features a 0.437-inch shank diameter and a 0.328-inch tap square size, sized for Number 2 adapter fitment in the WER 2 series. With a projection of 0.433 inches and a tap depth of 0.827 inches, it provides precise axial positioning during tapping operations. This adapter is used by machinists and tool room technicians working with pipe thread tapping applications on CNC machines, drill presses, and tapping heads where repeatable, quick-change tooling is required.

This adapter is suited for production and maintenance machining environments where 1/8-inch LS pipe threads are tapped into ferrous and non-ferrous workpieces. It integrates into WER 2 series quick-change tooling systems, allowing operators to swap taps without removing the holder from the spindle. Typical applications include pipe fitting manufacturing, hydraulic manifold production, and general metalworking shops that tap NPT-adjacent pipe thread forms at moderate volumes.

Key Features

• Quick-change interface eliminates tool-by-tool spindle removal during tap changes
• 0.437-inch tap shank diameter fits Number 2 adapter seat in WER 2 series holders
• 0.328-inch tap square size provides positive rotational drive without slippage
• 0.433-inch projection and 0.827-inch tap depth allow controlled thread engagement depth
• No coolant-through design — suited for external flood or mist coolant delivery setups
• Compact overall length of 1.811 inches (46 mm) minimizes spindle extension

Compatibility

Designed for use with WER 2 series quick-change tap holders accepting a Number 2 adapter with a 0.437-inch shank diameter. Compatible tap size is 1/8-inch LS pipe.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians familiar with quick-change tooling systems. Ensure the tap holder and spindle are fully de-energized and at rest before inserting or removing the adapter. Verify tap square engagement is seated fully in the adapter drive socket before beginning the tapping cycle. Follow the machine tool manufacturer's guidance for spindle speed and feed rate when tapping pipe threads.
