{"product_id":"bondloc-wl77-pipeseal-50ml","title":"Bondloc WL77 Pipeseal 50ml","description":"\u003cp\u003eSecuring metal pipe joints against leaks, pressure spikes, and chemical exposure requires a thread sealant designed for durability and ease of use. Bondloc WL77 Pipeseal 50ml delivers an industrial-grade sealing solution tailored for professionals in plumbing, HVAC, automotive repair, and plant maintenance. Designed specifically for coarse metallic threads, this anaerobic liquid sealant cures between tight metal interfaces, turning into a tough, thermoset plastic that completely fills the void between threads.\u003c\/p\u003e\n\u003cp\u003eUnlike traditional sealing methods like PTFE tape or hemp, which can shred, migrate, or contaminate fluid lines, Bondloc WL77 stays precisely where it is applied. Its thixotropic formula prevents running or dripping during assembly, ensuring clean, precise application on horizontal and vertical pipe runs alike. The inclusion of PTFE within the formulation provides excellent lubrication, making joint alignment smooth and straightforward without the risk of thread galling or seizing on stainless steel and other active metals.\u003c\/p\u003e\n\u003cp\u003eOnce applied, Bondloc WL77 offers an immediate low-pressure seal, allowing systems to be tested without long downtime. Over full cure, it develops a medium-strength bond capable of withstanding extreme pressure, heavy thermal cycling, and continuous mechanical vibration. Despite its exceptional holding power, the medium-strength formulation guarantees that pipe connections can be disassembled when maintenance or system modifications are required using standard hand tools.\u003c\/p\u003e\n\u003cp\u003eChemical resistance is a core benefit of Bondloc WL77 Pipeseal. It maintains its structural integrity when exposed to harsh industrial fluids, including gasoline, diesel, hydraulic oils, glycol solutions, water, and compressed gases. Whether you are installing new pneumatic lines, repairing hydraulic equipment, or installing gas and water mains, Bondloc WL77 Pipeseal provides a clean, reliable, long-lasting joint seal that protects your infrastructure against costly leaks and system failures.\u003c\/p\u003e","brand":"Bondloc","offers":[{"title":"Default Title","offer_id":55662793884024,"sku":"WL77-50ML","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0802\/8658\/1049\/files\/wl77.jpg?v=1789550331","url":"https:\/\/www.electrosw.co.uk\/products\/bondloc-wl77-pipeseal-50ml","provider":"Electro South West Ltd","version":"1.0","type":"link"}
