Fully compatible with all major refrigerants and compressor oils, it prevents leaks by forming resilient hydraulic seals that withstand heat, vibration, and pressure. OEM recommended and proven to keep HVAC and refrigeration systems leak-free without hardening or clogging, it’s the essential tool for professionals and DIYers aiming for flawless, long-lasting performance. ## Description It’s a Sealant: Nylon is a viscoelastic fluid made from refrigeration grade compressor oil. Gaskets coated with Nylon will never dry or become heat fixed to the surface. Threaded connections coated with Nylon will prevent high pressure leaks by forming a hydraulic seal. The compound always remains temperature and vibration resilient. It’s a Lubricant: Nylon can be used as a high tack assembly lube when installing shaft seals, O-rings, Schrader valves, ball valves, unloaders or other system components. Nylon is fully miscible and 100% compatible with the refrigerant and base compressor oils. NYLOG RED Is based on Mineral Oil and used on Ammonia, Propane, CFC or HCFC systems. NYLOG BLUE is synthetic ester oils fully compatible with all systems including those based on PVE oil, HFO refrigerants and CO2. Will Never Harden or Dry Will Not Clog or Contaminate Systems Fully Compatible and Miscible Used and Recommended by OEM’s Review: This is a must have if you are servicing the AC system on cars. - I had been ignoring my 20 year old AC system that leaked at the drier to low pressure line junction. No matter what I tried with different sizes of O rings, I could not hold vacuum longer than 3 hours. I decided to give this a go and pulled vacuum but it still didn't hold vacuum over night. I decided to just fill the system after drawing a vacuum with refrigerant with some sealer. Behold, it has been fine for past 2 months and I still have AC. I noticed this thing will soften plastic. My phone case has a spot where I got this snot on the surface and it is now permanently softened enough I can push with finger and it willl leave my finger print. I guess that is how this works. I would never mate any AC fittings without this ever again. Highly recommended. Review: Made my gauges finally work without leaking! - My neighbor is retired from HVAC and when I asked him what to use for leaky manifold gauges, he yelled " NYLOG RED"! Hopefully it will work because I cannot see paying a pro 10x the price that I can fix it for. Has a light oil smell and is a medium/thick consistency. Will update results soon! Also, my neighbor advised me to check and replace all the schrader valves and use the softer 1/4" manifold gauge gaskets (desertcart has a bag of 50 green gaskets for only $6!!!) instead of using the nylon gaskets. If I have time, I will do a video review on this.a ## Features - It’s a Sealant: Gaskets coated with Nylon will never dry or become heat fixed to the surface - It’s a Lubricant: Nylon can be used as a high tack assembly lube when installing shaft seals, O-ring - Schrader valves, ball valves, unloaders or other system components - NYLOG RED: Is based on Mineral Oil and used on Ammonia, Propane, CFC or HCFC systems. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 321 Reviews | ## Images ![Refrigeration Technologies RT200R Nylog- Gasket/Thread Sealant - Image 1](https://m.media-amazon.com/images/I/41CKIg1XYgL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is a must have if you are servicing the AC system on cars. *by M***. on April 18, 2019* I had been ignoring my 20 year old AC system that leaked at the drier to low pressure line junction.
