Sealing Devices Temporary Plugs
The Polyethylene Plug snap-in design protects exposed conduit and innerduct with ease.
A temporary conduit plug is a snap-in low-density polyethylene (LDPE) seal that protects exposed conduit and innerduct from weather, debris, and animal intrusion. Innovative Plastics’ polyethylene plug is purpose-built to protect standard ducts, inner-ducts, or terminators from the costly impacts of harsh weather conditions, on-site debris, and animal intrusion. Its tapered design makes installation quick and secure, while the scalloped ridges form a snap-in seal that resists accidental dislodging. A robust flanged lip at the base allows for easy plug removal, and every polyethylene plug features a built-in rope-tie. This built-in tie-off point makes it simple to attach mule tape or other lines, ensuring quick and convenient access whenever future needs arise.
Each plug is molded from Low Density Polyethylene (LDPE), a semi-pliable, high-impact, and chemically inert material characterized by extremely low moisture absorption. LDPE resists ultraviolet (UV) light, withstands ozone exposure, and endures wide temperature fluctuations, making it ideally suited for demanding underground or outdoor environments. These properties work together to provide a durable, long-lasting solution that reliably seals and safeguards your ducting infrastructure.

FAQ
Frequently asked questions
- What are temporary conduit plugs made of?
- They are molded from low-density polyethylene (LDPE) — a semi-pliable, high-impact, chemically inert material with very low moisture absorption that resists UV light, ozone, and wide temperature swings.
- What conduit sizes do temporary plugs fit?
- Twelve trade sizes from 1" (25 mm) to 8" (200 mm), covering standard duct and innerduct.
- How do the plugs stay in place and come back out?
- Tapered, scalloped ridges form a snap-in seal that resists accidental dislodging, while a flanged lip at the base makes removal easy.
- Can you pull a line through later?
- Yes — every plug has a built-in rope-tie so you can attach mule tape or pull-line for future access.
- Are they suitable for underground and outdoor use?
- Yes. LDPE's UV, ozone, and temperature resistance make these plugs well suited to demanding underground and outdoor environments.
