Product Description
Permabond A1058 is a high-viscosity anaerobic thread sealant in paste form — developed for coarse metallic pipe threads with the highest pressure-tightness requirements. The bond allows alignment of components during curing.
With 300,000 mPa·s, A1058 is almost a kneading compound — it does not drip, does not run, and remains precisely where it was applied. This consistency allows components to be aligned even during curing — important for long pipelines with defined connection positions.
The thread sealant withstands pressures up to the burst limit of the pipe, making it suitable for high-pressure applications. The WRAS approval qualifies A1058 for potable water systems — for example, in drinking water and distribution networks.
Pressure-tight up to the burst pressure of the pipeline — the highly viscous paste with 300,000 mPa·s fills coarse pipe threads completely and permanently. Allows alignment of components during curing. WRAS approved for potable water.

Frequently Asked Questions about Permabond A1058
Practical application and design questions — answered by SILITECH.
Permabond A1058 is an acrylic (anaerobic) adhesive with a viscosity of 300,000 mPa·s (paste) and gap filling up to 0.5 mm. High-viscosity paste thread sealant — fills coarse pipe threads, pressure-tight up to the burst limit. Anaerobic adhesives cure in the absence of air and in contact with metal — ideal for tightly toleranced metallic joints.
Anaerobic adhesives such as Permabond A1058 remain liquid in the bottle (air contact, oxygen) and only begin to cure after assembly under exclusion of air and in contact with metal. Curing starts from the metal surface and progresses into the bond gap. The product cures quickly on steel and copper; on stainless steel and zinc, Permabond A905 Activator may be beneficial.
Difficult to disassemble — Permabond A1058 is high-strength (8 N·m breakaway torque). Disassembly typically requires heating the joint to 200 °C or more. Designed for permanent bonding.
Permabond A1058 is approved according to WRAS drinking water approval . These certifications qualify the product for the respectively specified applications — for example, direct contact with drinking water for WRAS and KTW approvals.
Permabond A1058 typically achieves handling strength after 15 minutes and functional strength after 1 hour at 23 °C on M10 steel. Final strength is reached after 24 hours. On inactive surfaces (stainless steel, zinc) or at low temperatures, the curing time is extended — Permabond A905 Activator accelerates the process.
Permabond A1058 is a high-viscosity thread sealant (300,000 mPa·s (paste) viscosity, 0.5 mm gap filling, 8 N·m breakaway torque). Permabond A129 is a medium-strength gel (gel, 0.5 mm, 12 N·m breakaway torque) — lower viscosity, medium strength. Both belong to the anaerobic Permabond A series.
The choice depends on the application: Permabond A1058 (high-viscosity thread sealant); Permabond A129 (medium-strength gel); Permabond A1044 (fast curing); Permabond A118 (high-strength threadlocker). For inactive surfaces (stainless steel, zinc, aluminum), additionally use Permabond A905 Activator to accelerate curing.
