Review: After using Rectorseal T+2 for years without a leak, I tried this 5 version on air compressor fittings because it semi-hardens when it dries, which might take the abuse and vibration of compressor lines better. Like T+2 it works great and hasn't leaked so far. Rectorseal is great stuff, it's made in USA and has never failed me on natural gas, pressure washers, and air compressors. When Teflon tape is included with a threaded pipe product, I always throw it away and use Rectorseal.
Review: From SG. Does its job really well. Use it with teflon tape and I guarantee there’s no way it will leak even if u pressurised it immediately

## Questions & Answers

**Q: Can it be used for LP gas?**
A: I bought it for my new Natural Gas oven/range, You may want to read the below link :copy and paste below linkhttp://ows.rectorseal.com/product-data/RectorSeal-T-Plus-2/dstplus2.htm ***  I  see this product may not be what you want for LP GAS according to Rectorseal, you my be better off using their product called: Copy and paste below into Amazon's search box: Rectorseal 23631 1/4 Pint Brush Top T Plus 2 Pipe Thread Sealant

**Q: Can you use this on pvc cleanout adapter threads?**
A: Yes, you can.  Actually, Rectorseal would probably be one of the BEST products to use in this situation.  The product description states that it can be used on PVC and CPVC.  Rectorseal is a tan-colored, thick paste that acts as a lubricant and sealant on threaded connections.  It is NON-hardening, so it STAYS as a paste.  Since the PVC clean-out is a threaded connection, it should work just fine, without hardening or deforming your PVC pipe.

**Q: The picture and the description both say 4 oz (1/4 pint). the technical details say 8 ounces. which is it?**
A: It is 4 oz as described on the bottle.I do apologize for any confusion.Thank you!

**Q: Can we use for natural gas black pipe fitting or its only for brass fitting like valve etc. thanks**
A: Use it on black iron or galgalvanized.

Do not waste your time with gas tape. This does the job. Overpriced by about $15. Local hardware stores carry for much less.
