Leather body: Thickness Tolerance ±0.1mm

Component Specifications

Definition

A precision-engineered leather sealing component designed to prevent fluid or gas leakage between mechanical interfaces in industrial equipment. This flexible gasket creates a compression seal through controlled deformation under bolt load, maintaining integrity across temperature variations and mechanical vibrations.

Working Principle

Operates on compression sealing principle where controlled deformation of leather material fills microscopic surface imperfections between mating flanges. The leather's natural fiber structure provides both elastic recovery and creep resistance, maintaining sealing force over extended service periods.

Materials

Vegetable-tanned bovine leather, thickness: 2.0-3.0mm, density: 0.8-0.9 g/cm³, tensile strength: ≥15 MPa, elongation at break: 20-30%, oil resistance grade: ASTM D471 compliant.

Frequently Asked Questions

What are the advantages of leather over synthetic gasket materials?

Leather offers superior conformability to irregular surfaces, better creep resistance at moderate temperatures, and natural resilience that maintains sealing force over time without permanent deformation.

How should leather gaskets be installed?

Clean mating surfaces thoroughly, apply minimal sealant if required, torque bolts in crisscross pattern to specified values, and allow 24-hour settling period before pressure testing.
