Silicone Sealing Strip 39" 5mm
This cream-white silicone strip measures 39 inches long with a 5 mm diameter round profile. It is supplied new and designed for sealing doors, windows and equipment enclosures where a flexible, heat-resistant gasket is required. The material suits automotive, marine and general industrial uses.
Build Quality and Daily Use
The strip withstands temperatures from -94 °F (-70 °C) up to 482 °F (250 °C) without easy deformation or aging. Its smooth, low-odour surface resists ozone, mild acids, alkalis, oil and abrasion while staying soft and elastic. The solid round cross-section lets users splice custom-length sealing rings for irregular gaps.
Upgrade Path and Fit
The product replaces worn or hardened rubber seals that have lost elasticity or cracked under thermal cycling. The jump is worth it when the original gasket fails in high-heat zones such as exhaust systems, hydraulic fittings or oven doors. It is not suited for applications needing flat-profile tape, adhesive-backed foam or diameters other than 5 mm.

Questions about this item
What temperature range does the 5 mm silicone strip withstand?
The strip operates from -94 °F (-70 °C) up to 482 °F (250 °C), so it survives both deep-freeze and high-heat sealing jobs.
What groove or channel width fits the 5 mm round profile?
The solid rod measures 5 mm (0.19 in) in diameter, so a channel slightly wider than 5 mm will hold it without compression.
How do I join the 39 in length into a custom ring?
Cut the strip to the needed circumference, butt the ends together, and bond them with a silicone adhesive; the joint must cure fully before the seal sees pressure.
