Continuous flexible graphite packing for pump and valve enquiries.
The GRA-related entry offers flexible graphite packing and lists several square section sizes. It is a continuous packing offering separate from the supplier’s prepared graphite rings. An enquiry should identify reinforcement, section and required length, then request operating limits for the specific shaft motion and atmosphere instead of combining promotional maximum values.
