100M/100AL/124
 
Flexible Metallic Packing
 
100M/100AL/124

 

Styles 100M, 100AL and 124 are flexible metallic or crinkled packings. Designed for a wide variety of high speed, temperature, pressure and viscosity applications.
These strong, compressible packings demonstrate remarkably good shaft conformability and low friction characteristics for metallic packings.

 
Design Features
 

100M
Spirally wrapped, crinkled and folded layers of babbit foil are lubricated with oil and graphite and wrapped around a resilient neoprene core.

100AL
This spirally wrapped aluminum foil is wrapped around a high-temperature fiberglass core, making it ideal for high pressure and temperature applications.

124
A spirally wrapped solid aluminum foil is coated with oil and graphite for greater lubrication and heat dissipation, while reducing friction over the life of the packing.
