Refrigeration system accessories 48 flange drying filter

Product Details

In refrigeration and air conditioning systems, the white PTFE (Teflon) gasket is the standard sealing element used for the flange end cover of 48-series replaceable core filter drier shells (buckets). It ensures a critical, zero-leakage seal against high pressures, refrigerants, and refrigeration oils.

Application: Suitable for standard 48 series replaceable core filter drier shells.

Material: 100% Virgin PTFE (Polytetrafluoroethylene / Teflon), solid white color.

Approximate Dimensions: For standard 48-series flanges, the gasket typically has an Outer Diameter (OD) of approx. 150mm - 154mm and a thickness of 2.5mm - 3.0mm (varies slightly by shell manufacturer).

Temperature Range: Maintains reliable rigidity and sealing structure across extreme temperatures ranging from -60°C to +200°C.

High-Pressure Resistance: Harder than rubber, it withstands the high torque of M10 flange bolts without blowing out or deforming under high system pressures.
