Heng'S Butyl Tape
Heng's Butyl Tape: Trusted RV Sealing from an Industry Leader
When it comes to keeping moisture, air, and the elements out of your RV or camper, the quality of your sealant tape matters enormously. Heng's Industries has earned its reputation as one of the premier manufacturers of RV and marine sealing products — and their butyl tape lineup is a cornerstone of that legacy. Headquartered in Elkhart, Indiana — the heart of RV manufacturing country — Heng's butyl tape is trusted by both OEM builders and everyday RV owners across the United States and Canada.
What Sets Heng's Butyl Tape Apart
Heng's butyl tape is manufactured from butyl rubber, a synthetic material known for its superior durability and resistance to extreme conditions, making it ideal for creating waterproof seals in a variety of joints and openings. What makes Heng's stand out in this category is the breadth and specificity of their product line. They offer both trimmable and non-trimmable formulas, allowing RV technicians and DIYers to choose the right tape for their specific application — whether that's a clean cosmetic installation around a window frame or a heavy-duty lap joint seal along a roof edge.
Heng's trimmable butyl tape is a non-hardening, tough butyl elastic material that provides dependable and long-lasting sealing to surfaces such as rubber roofing, plastic, wood, and metal — creating an air-locking barrier that repels water and hot/cold air. Meanwhile, their non-trimmable tacky variants, such as the popular 5131 series, are engineered for applications where a more aggressive, high-tack bond is needed on contact.

Why Butyl Tape Is Essential for Your RV
Butyl tape provides a non-drying, tacky barrier that can withstand a wide range of temperatures, from intense heat to freezing conditions, and its UV resistance makes it an ideal choice for exterior applications where it will not degrade when exposed to sunlight over long periods. Heng's butyl tape can be pressed and formed to create an air- and watertight seal, and is made of non-hardening, elastic-based butyl for flexibility. These properties make it especially valuable for seasonal RV owners who need a seal that can handle temperature swings without cracking or pulling away.
Heng's represents affordable quality, long-standing credibility, and a commitment to service — principles that show clearly in their butyl tape products. Whether you're resealing a roof vent after a long camping season or assembling trim moldings during a full exterior refresh, Heng's butyl tape delivers reliable, professional-grade performance in a format that's easy to work with right off the roll.
