Обзор
Loctite 567 является one-part, anaerobic thread sealant предназначенный для metal pipe and fitting threads, особенно coarse threads и stainless steel where standard sealants may cure slowly or give unreliable sealing.
Applied to the male threads and assembled:
-
Fills the voids between metal threads to create a reliable seal
-
Помогает предотвратить leaks of oils, fuels, gases and many industrial fluids
-
Resists vibration, thermal cycling and pressure changes
-
Reduces risk of galling and seizure on stainless and other “difficult” metals
It is widely used in maintenance, repair and OEM assembly где вам нужно clean, reliable pipe thread sealing without tapes or loose pastes.
Основные характеристики и преимущества
-
Anaerobic, one-part liquid
Cures in the absence of air between metal threads, forming a thermoset plastic seal in the thread gap. No mixing required. -
Optimized for coarse threads & stainless steel
Создан для того, чтобы speed cure and improve sealing on less reactive metals and coarse threaded fittings, where ordinary sealants may struggle. -
High sealing reliability
Обеспечивает robust, pressure-tight seal for many common industrial fluids, helping reduce rework and call-backs. -
Non-shredding, non-migrating
Unlike PTFE tape, Loctite 567 does not shred into the system and won’t cold flow away from the joint once cured. -
Controlled disassembly
Threaded joints sealed with Loctite 567 can typically be разбирается с помощью обычных инструментов, simplifying maintenance while resisting vibration loosening in service.
Типичные области применения
It is used on metal pipe and fitting threads, particularly:
-
Hydraulic and pneumatic lines
-
Threaded adapters, couplings and manifolds
-
Instrumentation and control lines
-
-
Process & plant piping
-
Oil, fuel and coolant lines (where compatible)
-
General-purpose utility services and lubrication circuits
-
-
Maintenance and repair (MRO)
-
Retrofitting or replacing fittings on pumps, compressors and valves
-
Sealing threaded connections on tanks, reservoirs and skids
-
Not recommended for plastic fittings or pure oxygen systems. Always confirm compatibility with the specific fluid and operating conditions.
How to Use Loctite 567
Шаг 1 – Подготовка поверхности
-
Ensure threads are clean, dry and free from oil, old tape, rust and dirt.
-
Use a wire brush or thread cleaner to remove debris and old sealant if needed.
-
Degrease with a suitable cleaner for best performance.
Шаг 2 - Нанесите герметик
-
Shake the tube/bottle if required.
-
Применить непрерывная бусина of Loctite 567 to the male threads, covering the area that will be engaged in the joint.
-
For larger sizes, apply product around several threads to ensure full circumferential coverage.
Шаг 3 - Сборка
-
Immediately assemble the joint, tightening to the заданный крутящий момент or number of turns.
-
Small squeeze-out at the first thread or two is normal; do not wipe uncured product back into the joint.
Step 4 – Cure and return to service
-
Loctite 567 begins to fixture (reach handling strength) as it cures between the metal threads.
-
Full cure time depends on temperature, thread size, gap and metal reactivity.
-
Only apply full operating pressure and maximum temperature after the sealant has reached full cure according to your procedure.
Шаг 5 - Разборка
-
For service, loosen the joint with normal hand tools.
-
Clean the threads thoroughly, removing cured sealant before reapplying fresh product for reassembly.
Безопасность и обращение
-
Избегайте prolonged skin and eye contact with uncured product; may cause irritation.
-
Использование в хорошо проветриваемый area and avoid breathing vapours.
-
Носите подходящие СИЗ: chemical-resistant gloves and safety glasses as a minimum.
-
Do not pour uncured material into дренажи или естественные водные пути.
-
Хранить в оригинальная, плотно закрытая тара in a cool, dry place away from heat and direct sunlight.

Часто задаваемые вопросы
Q1: What is Loctite 567 mainly used for?
Loctite 567 is mainly used for sealing coarse metal pipe threads, особенно stainless steel and other passive metals, in hydraulic, pneumatic and process systems.
Q2: Can I use Loctite 567 on plastic fittings?
No. Loctite 567 is designed for металлические нити. On plastics, anaerobic products may not cure properly and some plastics may be stressed or damaged. Use a sealant specifically rated for plastic fittings.
Q3: How is Loctite 567 different from PTFE tape?
PTFE tape can shred and be pulled into valves or filters, and it doesn’t lock the threads. Loctite 567 cures to a solid seal in the threads, helping prevent leaks and micro-movement without leaving loose fragments.
Q4: Can Loctite 567 be used on fine threads?
It can seal both fine and coarse threads, but it is particularly optimized for coarse threads. For very fine or small threads, other Loctite thread sealants may be recommended depending on your application.
Q5: Is Loctite 567 suitable for high temperature or high pressure?
Loctite 567 is formulated for demanding industrial conditions, but specific limits depend on your system. Always consult technical data and test under actual temperature, pressure and fluid conditions.
Q6: How long does Loctite 567 take to cure?
Fixture and full cure times depend on metal type, temperature and thread size. Active metals at warm temperatures cure faster; passive metals and cold conditions cure slower. Allow sufficient time before applying full load.
Q7: Will Loctite 567 permanently lock the fitting?
Нет. Это резьбовой герметик, not a high-strength threadlocker. Joints can normally be disassembled with standard tools, although more torque may be needed than with an unsealed joint.
