Oakum is a dry, twisted, jute oakum made in rope form without tar or oil. Oakum is backed by laboratory and field research that has made it tops in quality, easy to handle and convenient to use. For many applications with PARSON PERMA SEAL, Oakum will save time and money, since it is made to pack solidly in minimum time. Double-yarn construction permits easy division of strands for use on small sealing applications.

Oakum conforms to Federal Specification HH-P-117 as published in the Federal Standard Stock Catalogue, Section IV Part 5. HH-P-117 was approved by the Director of Procurement on November 5, 1940 for the use of all departments and establishments of the Government. Copies are available from the Superintendent of Documents, Washington, D.C. The specification covers twisted jute packing only.

Oakum is made from thoroughly carded jute fiber and is practically free from hard, coarse fibers and extraneous matter. It is prepared in rope form with eight strands having a twist of approximately 1.25 turns per foot. Diameter is approximately two inches, weight is approximately 0.4 lbs. per foot and strand diameter is approximately 1/2 inch.

Since only dry jute should be used for sealing applications, Dry Oakum contains less than 8% oil by total weight of packing.

Oakum is sold and shipped in 50/lb. coils in cardboard containers. When fully unwound, a 50/lb. coil will yield approximately 1000 l.f. of 1/2" diameter rope. The very loose weave allows rapid absorption of PARSON PERMA SEAL in addition to ease of separation for insertion in small crevices.
