Protorque Welch Plug Steel Cup
The Protorque Steel Cup Welch Plug is an essential engine component designed to provide reliable sealing for sand casting core holes found in water-cooled internal combustion engines. These plugs are manufactured from high-quality mild steel with a protective finish to resist corrosion.
Features:
- Premium Steel Construction: Made from plated mild steel for durability and reliable performance
- Cup Design: Features a traditional cup-shaped profile that creates a secure interference fit
- Corrosion Resistance: Protected finish helps resist cooling system fluids and high temperatures
- Precision Engineering: Manufactured to exact specifications for proper fit and seal
Technical Details:
Welch plugs are press-fitted components that seal the holes created during the engine casting process. The cup-type design expands when properly installed to create a tight seal in the engine block or cylinder head casting holes. This prevents coolant from leaking out of the coolant passages and maintains the integrity of the engine's cooling system.
Installation:
Proper installation requires pressing the plug into the casting hole until it seats correctly. The interference fit between the plug and the hole creates the seal necessary to prevent leaks.
Note: This is a vehicle-specific component. Please verify compatibility with your specific engine application before purchase.
