Leader Style 1078

Description

Style 1078 is an off-white compressed, NBR/synthetic fiber sheet that is recommended for service where color contamination is a concern. It is also a good choice for cutting intricate gaskets requiring especially clean cuts. With a high-temperature parting agent as a standard surface treatment, 1078 is an excellent choice for general service gaskets.
