Valve Grinder With 3 Vacuum Pads - Pack of 4

Wood's Powr-Grip V12753 — Valve Grinder with 3 Interchangeable Vacuum Pads for Engine Valve Lapping — Pack of 4

The Wood's Powr-Grip V12753 Valve Grinder is a specialized vacuum tool designed to hold engine valves securely during lapping operations. Supplied with 3 interchangeable vacuum pads sized for different valves and valve seats, and constructed to resist the grease and corrosives associated with gas engine repair environments. The V12753 (SKU: 91106, Model: V12753) is manufactured by Wood's Powr-Grip. Sold as a Pack of 4.

The V12753 is a purpose-built engine repair tool — not a general-purpose vacuum cup or pickup tool. It is specifically designed for the valve lapping process in gas engine repair, where the valve must be held and rotated against the valve seat with consistent, controlled pressure to achieve a proper seal. The vacuum pad attachment provides a secure, centered grip on the valve face without the slippage risk of mechanical grippers, and the interchangeable pad set covers the range of valve sizes encountered in typical gas engine repair work.

Key Features & Benefits

3 Interchangeable Vacuum Pads — Covers Multiple Valve and Seat Sizes

The V12753 includes 3 interchangeable vacuum pads sized for different valves and valve seats, allowing the same tool to be used across the range of valve sizes encountered in gas engine repair without requiring separate tools for each valve size. Select the pad that best fits the valve face being lapped for a secure, centered vacuum attachment.

Effective Valve Holding During Lapping Operations

The vacuum pad attachment holds the valve securely and concentrically during lapping, providing consistent grip without the lateral slippage that can occur with mechanical grippers. This enables controlled, even lapping pressure across the valve face and seat contact area, contributing to a proper valve seal after lapping.

Grease and Corrosive Resistant Construction

The V12753 is constructed to resist the grease, oils, and corrosives associated with gas engine repair environments — where the tool will be exposed to engine oil, valve grinding compound, and other shop chemicals during normal use. This resistance extends the service life of the tool in engine repair shop conditions.

32°F–100°F Operating Range — Pack of 4

Rated for operation between 32°F (0°C) and 100°F (38°C) — the typical temperature range of an engine repair shop environment. Sold as a Pack of 4.

Common Applications

Engine Valve Lapping — Gas Engine Repair

Engine mechanics and rebuilders use the V12753 to hold intake and exhaust valves during the lapping process in gas engine repair and rebuild operations. The vacuum pad provides a secure, centered grip on the valve face for controlled lapping against the valve seat.

Multi-Valve Engine Repair

The 3 interchangeable pad set and Pack of 4 configuration make the V12753 practical for engine repair shops handling multiple engine types with different valve sizes, providing the right pad size for each valve without requiring separate tools.

Frequently Asked Questions

Q: What is the V12753 used for?
A: The V12753 is a specialized valve lapping tool for gas engine repair. It uses vacuum pads to hold engine valves securely during the lapping process, where the valve is rotated against the valve seat to achieve a proper seal. It is not a general-purpose vacuum pickup tool.

Q: Why does the V12753 have a narrower temperature range (32°F–100°F) than other WPG products?
A: The V12753 is designed for engine repair shop environments where the operating temperature range of 32°F–100°F covers typical indoor shop conditions. The vacuum pad materials are optimized for this range and the grease/corrosive resistance required in engine repair, rather than the wider temperature ranges needed for outdoor construction and glazing applications.

Q: Is this product made to order?
A: Yes. This product is made to order and all sales are final. Please confirm your application requirements before placing your order.
