SELCO SELF LOCATOR GASKETS
MIL-PRF-32187 TY3

MIL-PRF-32187 Type 3 specifies the requirements for self-locating gaskets, a specialized type of gasket designed to accurately align and position components during assembly while providing effective sealing. These gaskets are commonly used in applications where precise alignment is critical for optimal performance and reliability. The Type 3 classification within the MIL-PRF-32187 standard outlines the specific characteristics and performance criteria for these gaskets. They are engineered to ensure proper alignment and maintain consistent pressure distribution to create a reliable seal between components, which is essential for preventing leaks and maintaining system integrity. The adherence to MIL-PRF-32187 Type 3 standards guarantees that self-locating gaskets are manufactured to meet strict quality and performance requirements, making them a dependable choice for applications where accurate alignment and effective sealing are paramount, such as in military, aerospace, and industrial sectors.

The SELF LOCATOR gaskets are a complete stainless steel containment of a sealing element offering a true compression seal. The patented design gives you long term reliability without flange welding and eliminates misalignment on installation. Due to its universal sizing, one gasket fits all flange pressure classes, eliminating the chance of incorrect gasket selection.

The most important feature of the gasket is the high unit load generated by the narrow sealing area provides a considerably higher flange clamping pressure and a better seal at a lower clamping force.

The standard gasket material is 316 SS, with two (2) tracks of Flexible Graphite sealing elements. Specialty gasket material and/or sealing elements are available as options.

Associated with Mil-PRF-32187 TyIII (Ty3).
