록타이트 565

개요

Loctite 565 is a medium-strength, anaerobic thread sealant formulated as a white, paste-like compound for sealing coarse metal pipe threads. It cures in the absence of air between metal surfaces to form a tough polymer that fills the gaps between the flanks of the threads.

Once cured, Loctite 565:

• 예방하는 데 도움이 됩니다 액체 및 가스 누출 나사선 나선 구조를 따라

• 풀림을 방지합니다 진동 및 열 사이클링

• 나사산이 체결된 상태에서 보호합니다 corrosion, galling and seizure

It is a practical alternative to PTFE tape and traditional pipe dopes, providing cleaner assembly and more consistent sealing performance.

Why choose Loctite 565?

1) Designed for coarse pipe threads
The high viscosity, paste-like consistency of Loctite 565 makes it ideal for coarse metal threads commonly used on pipework and fittings. It packs into the spaces between thread flanks and stays where you put it.

2) 중간 강도, 사용 가능한 접합부
Loctite 565 gives a secure, pressure-resistant seal while allowing fittings to be disassembled with normal hand tools during maintenance or system modification.

3) Non-running, non-dripping formula
Because it is thixotropic and paste-like, Loctite 565 won’t run or drip on vertical or overhead joints. This reduces mess and keeps the sealant in the thread where it belongs, not inside the line.

4) Locks and seals in one step
By filling the clearances in the thread, the product both 자물쇠 the fitting against vibration-induced loosening and 물개 the path against leakage, often allowing you to eliminate separate locking devices and pipe dopes.

5) One-part, easy application
제공됨 single-component product, there is no mixing or special equipment. Apply from the tube or bottle, assemble the joint, and let it cure at ambient temperature.

일반적인 적용 사례

Loctite 565 is suitable for metal coarse-thread pipe connections in:

• 유압 및 공압 시스템

  • Manifolds, valve blocks, cylinders and actuators

• Plant utilities and general service

  • Water, air, inert gas and many non-aggressive industrial fluids

• Pumps, compressors and process equipment

  • Suction and discharge lines, lubrication and cooling circuits

• Maintenance & repair work

  • Replacement valves, gauges, plugs and fittings during MRO shutdowns

Loctite 565 is intended for 금속 스레드만 해당 플라스틱 파이프 나사산이나 순수 산소/강한 산화제 서비스에는 권장되지 않습니다.

How to Use Loctite 565

1단계 – 표면 준비

• Ensure threads are correctly cut and in good mechanical condition.

• Remove old tape, dried sealant, dirt and corrosion from the threads.

• 지워버려 heavy oil, grease and cutting fluid; a light residue may remain, but cleaner surfaces give more predictable results.

2단계 - 실란트 바르기

• Squeeze a small amount of Loctite 565 from the tube or bottle.

• 적용하십시오 연속 비드 around the male threads, covering the area that will be engaged.

• Avoid overloading the first thread to reduce the chance of excess product entering the system.

3단계 - 조립 및 방향 설정

• 조인트를 조립하고 지정된 토크로 조입니다.

• Orient elbows, tees and gauges to their final position.

• The paste consistency gives smooth tightening and helps avoid thread galling.

4단계 - 경화 및 압력 테스트

• 조인트가 취급 강도에 도달할 때까지 그대로 두세요.

• For many standard applications, you can perform a low-pressure test after a short time; for full design pressure and safety-critical joints, follow the cure times recommended in the data sheet and your plant procedures.

단계 5 – 분해

• During maintenance, fittings sealed with Loctite 565 are generally 일반 수공구로 분리 가능.

• After long service or elevated temperature exposure, extra leverage may be needed, but the product typically helps prevent severe thread seizure compared to dry assembly.

안전 및 취급

As with other anaerobic sealants, Loctite 565 should be handled with standard industrial precautions:

• 일으킬 수 있음 피부 및 눈 자극 접촉 시

• 장기간 또는 반복적인 접촉은 다음과 같은 결과를 초래할 수 있습니다. 피부 감작 일부 개인에게서

• 증기나 안개는 유발할 수 있습니다 경미한 호흡기 자극 환기가 잘되지 않는 지역에서

• 경화되지 않은 제품은 수생 생물에 유해함 통제되지 않은 상태로 방출될 경우

모범 사례

• 사용처 환기가 잘되는 지역.

• 피부와 눈에 닿지 않도록 주의하십시오; 착용하십시오 안전 안경 그리고 적합한 보호 장갑.

• 취급 후 및 음식 섭취나 음료 섭취 전에 손을 깨끗이 씻으십시오.

• Do not pour uncured product into drains or natural waterways.

• 원래의 밀폐 용기에 담아, 서늘하고 건조한 곳에 보관하십시오. 서늘하고 건조한 장소 열기와 직사광선을 피하여 보관하십시오.

자주 묻는 질문

Q1: What is Loctite 565 mainly used for?
Loctite 565 is used to seal and lock coarse metal pipe threads, preventing leaks of liquids and gases while resisting vibration and thermal cycling in industrial and plant systems.

Q2: How is Loctite 565 different from Loctite 577 or PTFE tape?
Loctite 565 is a white, paste-style sealant optimized for coarse metal threads, whereas Loctite 577 is a medium-viscosity liquid. Compared with PTFE tape, 565 doesn’t shred or extrude, and it provides a more uniform, permanent seal in the thread flanks.

Q3: Is Loctite 565 removable?
Yes. Loctite 565 is 중간 강도, so joints can typically be disassembled using standard pipe tools. It offers solid sealing and resistance to vibration but is not classed as a permanent, high-strength lock.

Q4: Can Loctite 565 be used on stainless steel and brass fittings?
Yes. Loctite 565 is suitable for steel, stainless steel, brass and other common metal fittings used in pipework. Always check for compatibility with any special alloys or surface treatments.

Q5: Can I use Loctite 565 on plastic pipe threads or plastic fittings?
No. Anaerobic products like Loctite 565 are designed for 금속 스레드 and may cause stress cracking in some plastics. For plastic piping or mixed metal/plastic joints, use a sealant specifically approved for plastics.

Q6: Does Loctite 565 withstand high pressure?
When properly applied and fully cured on correctly machined metal threads, Loctite 565 is designed for 고압 밀봉 in many industrial systems. Always validate performance in your own application and follow the limits in the Technical Data Sheet.

Q7: Do I still need PTFE tape if I use Loctite 565?
No. Loctite 565 is intended to replace PTFE tape and traditional pipe dope in most metal-thread applications. Using both together is unnecessary and can interfere with correct sealing.
