Review: Good tread loc sealant - Great product for thread loc sealer. Used on Cummins engine works great. Had good price with desertcart.
Review: Works great - I was a pipefitter for 36 years and couldn’t count how many screw joints I have made. This pipe joint compound works great. I used it on a hydraulic log splitter on all of the joints, fired it up and did not have any leaks at all. Very impressive

## Questions & Answers

**Q: does this dry hard/solid? can parts be removed after? i want to use this to install oil sensors in my car. thanks.**
A: Dries semi hard but hard enough that you can leave a fingernail imprint.  it's not difficult to disassemble anything.  I really like this stuff

**Q: Will it seal even with small amount of  hydraulic fluid present? Just incase I can't get it all cleaned out of the female threads,**
A: For LOCTITE 545 clean as much as possible in order to have the best possible result. I would recommend testing it in order to see how it behaves for your application. Also 545 is ideal for hydraulic system because it has no fillers so it will not contaminate.

**Q: Can I use this on the outside of a threaded line that is slowly leaking? Or only on the threads as it’s screwed in to prevent leaks?**
A: To my knowledge it will only work if you put it inside the threads - as you are assembling it.  And it works pretty well doing that.  Worked on a 3000+ psi hydraulic connection that was continually leaking.

**Q: I have a compressor tee fitting that I can't fully tighten to keep it oriented properly.  Will this seal that fitting?**
A: It probably will for a while , but it will leak again  . If  the fitting is loose you could try teflon tape or you could try to tap the hole out a little and try to turn the fitting one complete turn to get it to tighten up.

### ⭐⭐⭐⭐⭐ Good tread loc sealant

### ⭐⭐⭐⭐⭐ Made what I though impossible come true!
*by A***R on May 10, 2025*

Just got done using the Loctite 545 with primer 7471 (Required with stainless steel) and also used 5452 (Gel Version, No primer required) and they are awesome. What "I" key word "I" as a novice could not do with teflon tape and pipe dope these products were able to. Not only do they seal really well, but they also create a tight bond like other loctite glues. Again, these two products are specifically designed for Pneumatic use. IMOP, they are very expensive and not practical for everyday useI on a job site. I just got tired of taking my airline pipes, cleaning with wire brush and acetone and reassembling/assembling multipule times. I would like
