Product Overview

Pipe seal A2577 is used in the sealing of all types of threaded connections against water, oil, gases and most common materials conveyed by metal pipes. It is used on most hydraulic, pneumatic, oil, water and gas connections. This is a medium strength pipe-sealant which provides a non-shrink, instant, low pressure seal on tightened fittings.


Unlike most pipe seal sealants this is produced from the latest non-hazardous technology, so there are no hazard symbols or risk and safety phrases for this product. This pipe seal can comply with even the most stringent health and safety requirements.

Curing information

Pipe seal A2577 is a high-viscosity thixotropic gel paste which cures rapidly, sealing instantly to 10,000 psi (689 bar) through its anaerobic cure system in contact with metals in the absence of air (oxygen).

When cure speed is extended due to low temperatures or inactive surfaces, an activator can be used. The best results are found if A2577 is applied to a second or third threadform.

Once fully cured this pipe seal can resist pressures of up to 10,000psi, whilst maintaining a virbation proof seal that is resistant to most chemicals and corrosion.

Directions for use

  1. For optimum performance surfaces should be clean and free of grease (internal and external)
  2. If the material is an inactive metal consider using activator
  3. Shake the product thoroughly before use
  4. Apply the product to the male fitting on the leading threads in a 360º bead, leave the first thread free, making sure all voids are full. For bigger threads apply more product accordingly and putting a bead on the female
  5. Assemble and tighten as required
  6. Properly tightened fittings will seal to moderate pressures instantly. For maximum resistance allow a minimum of 24 hours to cure

Disassembly information

  1. Remove with standard hand tools
  2. In circumstances where hand tools do not work, use localized heat to bolt or nut, disassemble while hot

Cleaning information

To remove cured adhesive please use a combination of solvent and abrasion such as a wire brush.
