Stat-O-Seal NAS1523

The NAS 1523 Stat-O-Seal is designed with a pre-calculated interference factor built into the teardrop shaped elastomeric seal designed for applications requiring NAS 1523 conformance. 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.

NAS 1523 Stat-O-Seal Features:

Parker NAS 1523 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.

• 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 re-torqueing
• Long reliable service and a high level of reusability
• Rubber/bolt interference provides for easy assembly
