RS PRO Pipe Sealant Liquid for Pipe Sealing 50 ml Tube

If you need a quick and easy way to protect your piping systems from contamination, choose this anaerobic S77 pipe sealant from RS PRO. Just apply it to the metallic surface of your pipes to automatically seal threaded connections.

The sealant cures in less than 15 minutes, so it's a quick-acting solution that will save you time. The high-viscosity formula means it can resist up to 350 bar of pressure when fully cured after three to six hours, making it suitable for heavy-duty applications.


This product forms a secure, leak-free seal that won't contribute to oxidisation or corrosion in your pipe fittings. You'll often find this type of sealant used in plumbing and gas pipework.
