Its proprietary aluminized silicone formula creates a flexible, durable bond that reduces air gaps and friction noise while accommodating thermal expansion. Easy to apply with a caulk gun, each tube covers up to 124 linear feet, making it a must-have for professional-grade radiant heat installations. ## Description 12 ounce Tube of Aluminum Thermal Conductive Sealant Used to seal PEX tubing into Aluminum Heat Transfer Plates and Track Panels. Aluminum Thermal Conductive Sealant is a proprietary aluminum based sealant used to displace air gaps and promote heat conductivity between materials in radiant heating applications. When cured, the sealant leaves a permanently flexible layer, able to compliment joint movement during thermal expansion. Use of the sealant is also beneficial for mitigation of friction noises that can result from expansion of PEX tubing within plates or other materials. Applications/Instructions: Application of an 1/8" bead of sealant inside of the omega shaped radiant heat transfer plate is recommended. Each 12oz tube can apply an 1/8" bead of sealant for an approximate length of 124 linear feet. Sealing of Pipe or Tubing in Aluminum Heat Transfer Plates: Just prior to insertion of pipe or tubing, apply a ¼” continuous bead of ALUMINUM THERMAL CONDUCTIVE SEALANT to bottom of the plate groove. Permanently affix heat transfer plate to substrate surface (subfloor, sleeper tracks, joists, studs, etc.). Prevent movement of pipe or tubing until sealant has fully cured. Sealing Tubing and Creating a Flush Thermal Bridge for Heat Transfer Panels: Apply bead of ALUMINUM THERMAL CONDUCTIVE SEALANT to sides of exposed tubing. Use a plastic putty knife to trowel sealant level with the panel surface. Note: PEX tubing should be secured prior to applying the sealant as to prevent tube from shifting while sealant is curing. Bridging Material Layers for Thermal Conductance: Apply sealant to one or both material layers being adjoined. Use of a trowel to level sealant prior to adhering materials is recommended to ensure adequate surface coverage. Adhere and maintain pressure between material layers to devoid air gaps, as possible. Materials must be clamped or fastened together until sealant has fully cured. ## Features - Proprietary Aluminized Silicone Sealant - Seals PEX Tubing to Radiant Heat Plates ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079X2K54V | | Best Sellers Rank | #1,878,432 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #3,324 in Hardware Sealers | | Brand | Radiant Heat Store | | Brand Name | Radiant Heat Store | | Compatible Material | Aluminum, Plastic | | Customer Reviews | 4.2 out of 5 stars 2 Reviews | | Item Dimensions | 13 x 2 x 2 inches | | Item Form | Bead | | Item Weight | 12 Ounces | | Item dimensions L x W x H | 13 x 2 x 2 inches | | Manufacturer | Radiant Heat Store | | Material | Aluminum | | Material Type | Aluminum | | Number of Items | 1 | | Part Number | RHS-ATCS | | Style | Compact | | Style Name | Compact | | Surface Recommendation | Metal, Subfloor, Construction Materials | | UPC | 710308257265 | | Water Resistance Level | Not Water Resistant | ## Product Details - **Material:** Aluminum - **Brand:** Radiant Heat Store - **Style:** Compact - **Item Weight:** 12 Ounces - **Item dimensions L x W x H:** 13 x 2 x 2 inches ## Images ![12oz Tube Aluminum Thermal Conductive Sealant for Radiant Heat Transfer Plates/PEX from Radiant Heat Store - Image 1](https://m.media-amazon.com/images/I/71YhetgeNfL.jpg) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/101223218-12oz-tube-aluminum-thermal-conductive-sealant-for-radiant-heat-transfer](https://www.desertcart.vu/products/101223218-12oz-tube-aluminum-thermal-conductive-sealant-for-radiant-heat-transfer) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-09*
