what is the equivalent permatex product to loctite 638
I've seen so many people go confused nigh Permatex and Loctite, that I finally decided to do a comprehensive post on these two.
Today nosotros'll be looking at both brands' threadlockers and thread sealants. Mutual identical products here are:
- Loctite 565 vs Permatex 56521 for thread sealants
- Loctite 242 vs Permatex 24200 for threadlockers (medium strength)
- Loctite 515 (or 518) vs Permatex 5183 for anaerobic flange sealants
Did you lot notice something in their numbers? Yep, they're made like this for easier cross-reference.
Permit's have a look at the differences between them – if whatever at all in some cases 🙂
A little trivia: Loctite bought Permatex in 1972, and around 2000 they sold them dorsum. Currently, Permatex's owner is Illinois Tool Works – the same company that owns Hobart and Miller welders, Tapcon fasteners and many more than.
Loctite 243 Best medium strength threadlocker. Oil resistant and holds things tighter. Improvement over 242 and Permatex 24200.
Loctite 565 Loctite's most widely used thread sealant. Withstands pressure, temperature and prevents leaks.
Permatex 56521 Absolutely the same equally Loctite'southward rival production. I guess become information technology if you lot prefer blue over cherry messages, as it's equally powerful and useful.
Permatex 51813 Fills bigger gaps which can be important in some cases. Otherwise has the same function and properties equally Loctite 515/518.
Permatex vs Loctite:
Threadlockers
The threadlocker products from both brands are virtually the same. Past 'most' I mean that with general utilise, you won't notice any pregnant divergence.
There are, nevertheless, ii small details.
First, Permatex has gel twist type threadlockers similar the 24010.
It's substantially the same product like the Permatex 24200 and Loctite 242. Yet, it introduces two improvements:
-
Supports bigger fasteners: 1/4″ to ane″ instead of the usual 1/4″ to 3/four″.
-
The gel is easier to utilize – specially with vertical applications.
2d, Permatex is a bit slower in terms of fixture time. It will set in at around the 20-minute mark while Loctite 242 does the same after 15 minutes. Both fully cure after 24 hours.
Note: If y'all want a medium strength threadlocker and don't care virtually gels, cheque out Loctite 243. Information technology's an improved version of both 242 and 24200 – primerless and oil resistant.
Keeps fasteners even tighter, and doesn't require you to practice a thorough cleaning on the threads beforehand.
Loctite 243 Best medium strength threadlocker. Oil resistant and holds things tighter. Improvement over 242 and Permatex 24200.
Simply really, there isn't much divergence betwixt the whole lineup of Permatex or Loctite threadlockers. They fifty-fifty share the aforementioned color scheme for the forcefulness/hold of their threadlockers:
-
Royal for depression strength
-
Blue for medium strength
-
Red for loftier (permanent) strength
The bluish threadlockers will be OK for ninety% of your projects. If you lot demand more info on Loctite'southward products, I've compared their threadlockers already.
You lot tin check the Permatex 24200 and read what people say nearly it. However, as I said, I recommend Loctite 243 over any other medium strength production.
Thread sealants:
Permatex 565221 vs Loctite 565
Ii favorites of plumbers and mechanics – merely not only. You'd demand these 2 for a variety of pipe/fitting sealing jobs from waste handling, to hydraulic lines, to brake fittings, air conditioners…
I'll be frank: they're literally the aforementioned thing.
Both work with any NPT (National Pipe Thread) that's up to 2″ – that'south 5cm for those using the metric system.
Also, both withstand pressure of up to 10,000 psi.
Surprise, surprise – both of them likewise have a temperature range of -65°F to 300°F.
I mean, if y'all have whatever specific brand preference, get ahead and buy whichever you feel better about. Even the tubes accept the same design.
The important thing is that you lot won't have whatever leakages and will do good from your benefits non rusting/corroding after you employ either of them.
Loctite 565 Loctite's most widely used thread sealant. Withstands force per unit area, temperature and prevents leaks.
Permatex 56521 Admittedly the same as Loctite's rival product. I judge become it if y'all prefer blue over ruby letters, equally it'southward as powerful and useful.
Loctite 518 vs Permatex 5183 gasket makers:
Pocket-sized differences
OK, so this time we have a little more than diversity that deserves mentioning. I had to dig in Henkel's official site to find it
A small divergence betwixt this Loctite and the 5183 analogue is the gap support:
Loctite 518 fills gaps up to 0.25mm (0.01") while Permatex 5183 goes wider with gap support of up to 0.38mm (0.015").
Both of these are anaerobic gasket makers/flange sealants. You lot desire to use them with metal parts and machinery. Aluminum, iron, steel – someday you need a quick repair y'all can utilise either of these.
Probably you've noticed that Loctite 518 is very hard to find – both in physical stores and online…
A more accessible substitute is Loctite 515. It works the same for almost situations, with 2 caveats.
Offset, it's subpar for aluminum flanges. Second, it sets faster so it might cure quicker than the other two with more active metals like brass.
Permatex 51813 Fills bigger gaps which tin can be important in some cases. Otherwise has the same office and properties as Loctite 515/518.
Closing words:
Cross-reference table & definitions
I won't lie – much as I like using both brands' products, all the classification going on can turn anyone's caput spinning. Why would I be writing this article otherwise, right?
If you want a somewhat consummate Permatex vs Loctite cross reference tabular array, i already exists. You tin can bank check it on Permatex's official site.
Some people don't brand a difference between threadlockers and thread sealants. As I've compared Loctite and Permatex in both of these uses, allow'southward bring upwards some short definitions.
Threadlockers: These are adhesives which you utilize on bolts/fasteners/screws so they stay tight. In addition, both brands' threadlockers help against corrosion due to their protective formula.
Thread sealants: Here you seal two connectors. As I mentioned, these are mostly pipes – from plumbing, to air conditioning or even projects dealing with annihilation automotive.
With gasket makers, I recommend you to refer to Permatex's guide on what mistakes to not make when using them.
