Manway Gasket Installation & Bushing Adjustment

Introduction

In this blog post and its companion videos, we explore the essential steps for installing manway gaskets and fine-tuning the bushing to achieve a secure, leak-proof seal. By adhering to these best practices and focusing on precision, operators can ensure a dependable installation, safeguarding against leaks and minimizing product loss with confidence.

Gasket Installation

• The gasket groove channel must be carefully positioned over the lip of the manway cover to ensure a secure fit.
• For optimal sealing, avoid using loose-fitting or damaged gaskets.
• Proper alignment of the manway cover inside the collar is essential for effective sealing.
• Position the clamp arm and hand tighten the wing nut. Excessive force can damage the gasket, cover, and component parts.
• If the product leaks around the cover while the vessel is filling, stop the process and recheck for proper sealing of the cover and gasket.

Manway Bushing Adjustment

• Loosen the wing nut before making other adjustments.
• Identify and loosen the set screw with an Allen wrench.
• Use a crescent wrench to turn the bushing left or right to adjust the positioning of the manway cover up or down.
