Parker's fastener seal designs found in the Stat-O-Seals feature an elastomeric sealing element molded in place within a metal retainer (washer). Stat-O-Seals are intended to seal immediately under the head of a bolt and conform NAS1523. The Stat-O-Seal 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 Features: Parker Stat-O-Seals 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, NAS1523 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-Seals are designed to seal beneath the head of the fastener as shown for both internal and external pressure and vacuum systems. Stat-O-Seals offer users long and reliable service, a high degree of reusability and easy assembly. The Stat-O-Seal’s unique features provide many advantages and benefits as shown below: • No machined O-ring grooves are required in the mating flange • Precisely controlled optimum percent squeeze eliminates over compression • The retainer edge is visible after installation allowing for easy visual inspection and reducing failures caused by missing seals • The self centering design provides easy and accurate placement of the seal • The solid metal to metal contact improves joint stability and eliminates
