The Parker Hose Products Division (HPD) announced today the introduction of an alternative formulation for its inner tube compound for rubber hose. This new formulation has been rigorously validated through Parker’s manufacturing process to ensure full compliance with ISO 18752 standards and all performance specifications detailed in the Parker Hose Catalog 4400.
HPD retains the discretion to alternate between these inner tube formulations as operational needs dictate. Part numbers will remain unchanged, and this update is effective immediately as a running change. Projected implementation dates for each part number are provided below.
