It’s fully WRAS approved, safe for potable water, and effective on wet or dry surfaces. Heat-resistant and versatile, it offers a thick, moldable paste ideal for plumbing repairs on metal, plastic, and stone, making it the go-to choice for reliable, professional-grade sealing in heating and water systems. ## Description Product Description MC-XS may be used as a jointing compound on hot and cold-water services, including potable water, in place of traditional materials. Reinforcement is generally not required, but reinforcement fibre may be used on larger pipe sizes. The use of reinforcement material is advisable for larger leaks and higher pressures.

Review: Does what it says - As others have said, it is very similar to silicone. But as a DIY'er, i couldn't justify buying a large tub of jointing compound for the odd job around the house. This does the job just fine. I've fitted two radiators and an outside tap, no leaks so far. Highly recommended! Review: NOT QUITE SILICONE - AND THATS A GOOD THING!!! - Comparison: Adey MCXS vs. Standard Silicone 1. Consistency Adey MCXS: Thick, moldable paste. Standard Silicone: Thinner, designed for beads or strips. 2. Wet Surface Adhesion Adey MCXS: Can be applied to damp or wet surfaces. Standard Silicone: Requires a bone-dry surface to stick properly. 3. WRAS Approval Adey MCXS: Fully approved for drinking water Standard Silicone: Most are not safe for drinking water contact. 4. Heat Resistance Adey MCXS: Specifically designed for high-temperature heating systems. Standard Silicone: Varies; often not tested for central heating cycles. 5. Removal Adey MCXS: Does not set rock-hard; joints can be undone later. Standard Silicone: Can bond very strongly, making future disassembly difficult. ## Features - Suitable for compression and screw fittings - Ideal for most surfaces –wet or dry - Safe for use with drinking water - Fully WRAS approved ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BHJKNNFJ | | Best Sellers Rank | 134,623 in DIY & Tools ( See Top 100 in DIY & Tools ) 1,552 in Sealers | | Brand | Adey | | Compatible Material | Metal, Plastic, Stone | | Customer Reviews | 4.2 out of 5 stars 120 Reviews | | Item Dimensions | 14.3 x 2.8 x 3.6 centimetres | | Item Form | Paste | | Item Weight | 57 Grams | | Item dimensions L x W x H | 14.3 x 2.8 x 3.6 centimetres | | Item weight | 57 Grams | | Manufacturer | Adey | | Manufacturer Part Number | MCXS | | Material | Adhesive / Sealant | | Model Number | MCXS | | Number of Items | 1 | | Product Warranty | 12 Months | | Style | Compression | | Style Name | Compression | | Supported Standards | WRAS | | Surface Recommendation | Various | | Unit Count | 1.0 count | | Water Resistance Level | Waterproof | | Water resistance level | Waterproof | ## Product Details - **Brand:** Adey - **Item dimensions L x W x H:** 14.3 x 2.8 x 3.6 centimetres - **Item weight:** 57 Grams - **Material:** Adhesive / Sealant - **Style:** Compression ## Images ![Adey MCXS - External Leak Sealant & Jointing Compound,50ml - Image 1](https://m.media-amazon.com/images/I/61Y5JB3IysL.jpg) ![Adey MCXS - External Leak Sealant & Jointing Compound,50ml - Image 2](https://m.media-amazon.com/images/I/51zXkDjVHML.jpg) ![Adey MCXS - External Leak Sealant & Jointing Compound,50ml - Image 3](https://m.media-amazon.com/images/I/51qfd10jh+L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Does what it says *by J***N on 24 May 2025* As others have said, it is very similar to silicone.
