For best performance, pair with these Loxeal products:
Loxeal Cleaner 10 Degreaser: clean and degrease the threads first for maximum bond strength.
Loxeal Activator 11: speeds curing on stainless steel, plated and other passive metals, in cold conditions, or across larger gaps.
Loxeal 85-86 Thread Sealant High Temperature Anaerobic Adhesive 50ml
Loxeal 85-86 is a high strength anaerobic adhesive for locking and sealing threaded joints on all metals, in both free and forced matings. It maintains its sealing performance up to +200°C and offers high resistance to thermal shock, vibration, water, gas, oils, fuels, refrigerant fluids and many other chemicals – making it the choice for hot pipework, gas lines and demanding sealing jobs where standard sealants fall short.
Why choose Loxeal 85-86?
Seals and locks in one step with high mechanical strength
Keeps sealing up to +200°C (service range -55°C to +200°C)
Works on all metals, including free and press-fit assemblies
Resists thermal shock, vibration, fuels, refrigerants and many chemicals
Generous gap fill up to 0.30 mm on threads up to M56 / 2″
Green colour, fluorescent under blue light, for easy inspection
Certified and approved
Approved for gas-tight threaded joints to EN 751-1 (DIN-DVGW)
WRAS approved for contact with wholesome (potable) water
Compliant with the UBA (German Environment Agency) declaration for potable water use
BAM certified as a sealant in the presence of gaseous oxygen up to 20 bar at +60°C
Typical applications
Sealing threaded joints on gas, steam, hot water and heating pipework
Potable water fittings (observe the potable-water cure times below)
Refrigeration, fuel and industrial fluid lines exposed to heat and vibration
How to use
Clean and degrease both threads with Loxeal Cleaner 10 and allow to dry.
Apply a continuous bead circumferentially, 1–2 threads back from the leading edge, using enough product to give a complete seal.
Assemble and tighten the joint, then wipe off any uncured excess.
Allow to cure before pressurising. On passive surfaces or in cold conditions, pre-treat with Loxeal Activator 11 (this may reduce final strength).
Cure times at +25°C
Handling strength: 10–40 minutes
Functional strength: 6–12 hours
Full cure: 24–36 hours
Before contact with potable water: allow 24 hours at +20°C for brass, copper and cast iron; 7 days for stainless steel and aluminium

Important notes
Recommended for metal thread joints only – contact a technical service before use on other materials.
Do not contaminate the adhesive with metal; cut the nozzle to the required bead size.
The liquid product can damage coatings, some plastics and elastomers, and may cause stress cracking in some thermoplastics.
High strength – for disassembly, heat parts to +150°C/+250°C, use normal tools, then remove cured residue mechanically and clean with acetone.
Store in a cool, dry place at no more than +25°C and do not return used product to the container.
