Anaerobic gasket makers A136, HH190, MH196, LH197, MH199 and activators A905/ASC10 for flanges
Country: United Kingdom · Model: A136/HH190/MH196/LH197/MH199
Anaerobic gasket makers A136, HH190, MH196, LH197 and MH199 for flat rigid metal flanges of gearboxes, pumps, compressors and engines. A bead is applied to one surface, and after the parts are tightened the compound cures without air and forms a gasket in place.
- Purpose
- forming a gasket in place (FIP) on rigid metal flanges
- Grades
- A136 — general-purpose, 12 MPa; HH190 — flange sealant, 300 000 mPa·s, 6 MPa; MH196 — fast, heat-resistant, 10 MPa; LH197 — low strength, flexible, 5 MPa; MH199 — highly thixotropic, heat-resistant, 8 MPa
- Viscosity
- up to 500 000 mPa·s (MH196, 2 rpm)
- Activators
- A905, ASC10 — for all anaerobic grades

Description
Such a gasket does not shrink or relax, is not squeezed out, does not require retightening of the fasteners and preserves metal contact between the flanges, while the excess outside the flange remains liquid and is easily removed. A136 is red, general-purpose, with a shear strength of 12 MPa and a viscosity of 75 000 mPa·s at 2 rpm. HH190 is violet, 300 000 mPa·s, 6 MPa. MH196 is fast-curing and heat-resistant, up to 500 000 mPa·s, 10 MPa. LH197 is green, low-strength and flexible, 5 MPa, 50 000 mPa·s, for flanges that are disassembled regularly. MH199 is highly thixotropic and heat-resistant, 8 MPa, and stays in place on vertical surfaces. The activators A905 and ASC10 are suitable for all anaerobic grades.
How to choose
The grade is selected by the gap width, the temperature and the need for later disassembly. LH197 suits frequent disassembly, MH199 vertical surfaces, and MH196 fast curing at higher temperature, while A136 covers general tasks. A136 is supplied mainly to Europe, the Middle East and Australia, HH190 to the Americas and Asia, and the others worldwide.

FAQ
Which gasket maker suits frequently disassembled flanges?
LH197, a green low-strength flexible sealant, 5 MPa. It is also suitable for joints with small relative movements.
Which sealant does not run off a vertical flange?
MH199, a highly thixotropic heat-resistant compound, 8 MPa.
What is the viscosity of the gasket makers?
A136 has 75 000 mPa·s at 2 rpm, HH190 has 300 000 mPa·s, LH197 has 50 000 mPa·s, and MH196 up to 500 000 mPa·s.
How is a gasket maker better than a cut gasket?
It does not shrink or relax, is not squeezed out and does not require retightening of the fasteners. Metal contact between the flanges is preserved.
Why are the activators A905 and ASC10 needed?
They speed up curing on passive or coated metals, with large gaps and at reduced temperatures. They are suitable for all anaerobic grades.
