The Stat-O-Seal® fastener is designed with a pre-calculated interference factor built into the teardrop shaped elastomeric seal. The cross-
section free height of the rubber is greater than the metal retainer, providing the proper compression without squeezing the seal beyond its
elastic limit.
Stat-O-Seal fasteners are one-piece, molded-in-place seals with the rubber sealing element mechanically and/or chemically bonded to the
metal retainer. Parker's "Splined and Coined" mechanical bonding feature is used on many
600, NASI 523 and 610 series sizes. This feature ensures a positive attachment of the rubber to the retainer, eliminating missing or loose seal
elements associated with bonded seals. Stat-O-Seal fasteners are designed to seal beneath the head of the fastener for both internal and
external pressure and vacuum systems.
Stat-O-Seal fastener features and benefits include:
• - No machined O-ring grooves are required in the mating flange
• - Precisely controlled optimum percent squeeze eliminates over compression
• - Easy assembly. The self centering design ensures accurate placement of the seal.
• - The retainer edge is visible after installation allowing for easy visual inspection and reducing failures caused by missing seals
• - The solid metal to metal contact improves joint stability and eliminates re-torquing
• - Long reliable service and a high level of reusability
• - Rubber/bolt interference provides for easy assembly
