Rubber Grommet (1/2")

Mulberry CWD77-BOX – Rumsey 1/2" Rubber Grommet for Sealing Applications The Rumsey 1/2" rubber grommet (Mulberry CWD77-BOX) is designed for use in plumbing, electrical, and mechanical installations requiring a tight seal around penetrations. Manufactured from resilient rubber, it provides a durable interface between components and the surrounding structure, minimizing the risk of leakage and protecting against mechanical abrasion. This grommet is suitable for sealing 1/2" diameter holes and can be used in a range of field applications including pipe, tubing, or wire pass-throughs. Its material composition supports flexibility and compression, ensuring a secure, pressure-resistant seal under typical jobsite conditions. Product Specifications Inner Diameter: 1/2 in Material: EPDM or equivalent-grade rubber Application: Used for sealing circular cutouts in enclosures, panels, or wall penetrations in plumbing and electrical systems Mounting: Press-fit installation in drilled or punched 1/2" openings Function: Provides a physical barrier against moisture, vibration, and abrasion Installation Notes Install directly into a clean 1/2" opening. No adhesives or additional sealing materials are required. For best results, align the grommet flush with the mounting surface. Use appropriate hand tools for positioning to avoid tearing or deformation during insertion. Field Use Considerations This component is commonly used in equipment cabinets, utility boxes, or wall penetrations where mechanical protection and environmental sealing are required. It is appropriate for both interior and protected exterior conditions where exposure to water or minor pressure changes may occur. Contractor Relevance Ideal for retrofit or new installations in commercial and residential applications. Frequently used in boiler rooms, panel assemblies, and mechanical closets where code compliance and sealing integrity are priorities.
