Its thixotropic acrylate formula ensures easy, drip-free application and immediate sealing against low pressures. Compatible with both active and passive metals, it offers heat and chemical resistance, making it ideal for professional-grade plumbing and industrial use. Packaged in a convenient 50ml amber bottle, it’s the go-to solution for reliable, durable thread sealing. ## Description LOCTITE 577 - Universal thread sealantLOCTITE's thread sealant is medium strength and can be used universally for conical and cylindrical threaded connections. The heat resistant metal adhesive seals and secures at the same time: gaps are filled and an immediate sealing effect against low pressures is achieved for metal pipe connections. Although the thread sealant is liquid, the thixotropic properties prevent the adhesive from running off for easy application. As a universally applicable sealant, the metal adhesive is heat resistant and withstands both chemical and thermal stresses. The plumbing sealant can be used for all passive metals such as stainless steel and for active metals such as copper.To use, clean all surfaces with a solvent-based cleaner and allow to dry. In case of inactive metal surfaces or a too slow curing speed, spray with an activator (LOCTITE SF 7471 or SF 7649). Apply the adhesive 360Β° in a ring on the end of the male thread, leaving the first thread free. Spread adhesive down to the top of the thread to fill the gaps. For larger threads, adjust the quantity accordingly and also apply the product 360Β° in a ring on the internal thread. Screw-in pipe threads as usual and tighten with a tool until alignment is correct. With properly tightened connections, an immediate sealing effect against low pressures is achieved. For maximum pressure and solvent resistance, allow the product to cure for at least 24 hours.The Product Benefits at a Glance:For securing and sealing threadsFor active and passive metalsEasy application and immediate sealing effectBased on acrylateColour: YellowFormat: 50ml ## Features - Ideal for fast applications at low temperatures - Medium substrate to be sealed and metal instant low pressure seal - Designed for easy use ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Loctite | | Part number | 2068186 | | Item Weight | 90 g | | Product Dimensions | 4.7 x 4.9 x 14.1 cm; 90 g | | Item model number | 577 | | Size | 50 ml | | Color | Amber | | Material | Acrylate | | Volume | 50 Milliliters | | Item Package Quantity | 1 | | Number Of Pieces | 1 | | Measurement System | Metric | | Special Features | Heat Resistant | | Specific uses | Metal-to-Metal Bonding, Threaded Connections | | Included components | 1 | | Batteries Included? | No | | Batteries Required? | No | ## Product Details - **Brand:** LOCTITE - **Specific uses for product:** Metal-to-Metal Bonding, Threaded Connections - **Material:** Acrylate - **Compatible material:** Metal - **Item form:** Gel ## Images ![Loctite K978773 577 Fast Cure Medium Strength Pipe Seal, Multi-Colour, 50 ml - Image 1](https://m.media-amazon.com/images/I/71QCim4SGlS.jpg) ![Loctite K978773 577 Fast Cure Medium Strength Pipe Seal, Multi-Colour, 50 ml - Image 2](https://m.media-amazon.com/images/I/71nkZVt-65S.jpg) ![Loctite K978773 577 Fast Cure Medium Strength Pipe Seal, Multi-Colour, 50 ml - Image 3](https://m.media-amazon.com/images/I/81J1fXB8kIL.jpg) ![Loctite K978773 577 Fast Cure Medium Strength Pipe Seal, Multi-Colour, 50 ml - Image 4](https://m.media-amazon.com/images/I/81Jp1bw6oRL.jpg) ## Frequently Bought Together - LOCTITE 577, Medium Strength Industrial Adhesive for Thread Sealing, Universal Liquid Adhesive for Pipes and Metal Threads, Chemically Resistant Thread Sealant, 50ml - LOCTITE 55 Pipe Thread Sealant, Non Curing Plumbers Tape for Plumbing Pipes and Fittings, Reliable Fast Action Cord for Metal and Plastic, 160m - LOCTITE 55 Pipe Thread Sealant, Non Curing Thread Sealant for Plumbing Pipes and Fittings, Reliable Fast Action Pipe Sealant for Metal and Plastic, 50m --- ## 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.pl/products/449905613-loctite-k978773-577-fast-cure-medium-strength-pipe-seal-multi](https://www.desertcart.pl/products/449905613-loctite-k978773-577-fast-cure-medium-strength-pipe-seal-multi) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-03*
