The OEM PS-SEAL 45x65x10 Double Lip PTFE is designed for rotary shaft applications requiring reliable sealing around a 45 mm shaft within a 65 mm housing bore.

Unlike conventional rubber oil seals, the sealing elements are manufactured from PTFE (Polytetrafluoroethylene), a material known for its low coefficient of friction, broad chemical resistance, high-temperature capability, and suitability for selected dry-running or marginally lubricated applications.

The double-lip configuration provides two sealing elements. Depending on the actual design and installation orientation, the second lip may provide:

• Additional media retention
• Separation of two process fluids
• Protection against external contamination
• Backup sealing capability
• Improved sealing stability in demanding service

The exact lip orientation, lip loading method, case construction, filler grade, spring arrangement, sealing direction, and intended duty must be verified against the actual product drawing or original seal before installation.

PTFE rotary shaft seals are commonly selected for use with:

• Aggressive chemicals
• Solvents
• Synthetic oils
• Mineral oils
• Hydraulic fluids
• Food-processing media
• Pharmaceutical process fluids
• High-temperature lubricants
• Dry or low-lubrication applications
• High-speed rotating shafts

PTFE offers excellent chemical resistance and low friction, but sealing performance depends strongly on shaft finish, shaft hardness, concentricity, runout, installation quality, pressure, speed, temperature, filler composition, and lip orientation.

The dimensions are:

Shaft diameter: 45 mm

Housing diameter: 65 mm

Seal width: 10 mm

The 45 × 65 × 10 mm size is suitable for compact-to-medium pumps, mixers, agitators, gearboxes, process machinery, food equipment, pharmaceutical systems, and specialized OEM applications.

📊 Specifications

Brand: OEM

Model / Type: PS-SEAL

Size: 45 × 65 × 10 mm

Type: Double-Lip PTFE Rotary Shaft Seal

Material: PTFE (Polytetrafluoroethylene)

Profile: PS-SEAL Double Lip

Construction: Manufacturer-Specific PTFE Rotary Shaft-Seal Assembly

Lip Design: Double PTFE sealing lips; verify exact orientation, geometry, and function

Dust Lip: The second lip may serve as an exclusion, separation, or backup lip depending on the actual design

Spring Type: Verify from the actual seal construction; PTFE seals may use formed lip loading, spring energization, or another manufacturer-specific arrangement

Case Material: Verify actual metal or composite case construction

PTFE Grade: Verify virgin, glass-filled, carbon-filled, bronze-filled, or food-grade compound as applicable

Shaft Diameter (ID): 45 mm

Housing Diameter (OD): 65 mm

Width: 10 mm

Pressure Capability: Depends on lip design, support arrangement, shaft speed, temperature, and manufacturer specification

Lubrication: Suitable for compatible lubricated, marginally lubricated, or selected dry-running service depending on the actual design

Temperature Range: Common PTFE sealing compounds can support a broad temperature range, but the actual limit must be verified against the filler grade, case material, fluid, speed, pressure, and operating conditions

Speed Consideration: Suitable speed depends on shaft diameter, shaft finish, lip loading, lubrication, temperature, pressure, runout, and PTFE compound

Shaft Surface Requirement: A smooth, hardened, damage-free sealing surface is important for reliable PTFE seal performance

Application Class: Chemical, Food, Pharmaceutical, High-Temperature, and Specialized Industrial Service

Standard: Metric Specialized PTFE Rotary Shaft Seal

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• OEM PS-SEAL 45x65x10
• 45x65x10 Double-Lip PTFE Seal
• 45 mm Shaft PTFE Oil Seal
• PTFE Rotary Shaft Seal
• Double-Lip Chemical-Resistant Seal
• Food-Processing PTFE Shaft Seal
• Pharmaceutical Equipment Shaft Seal
• High-Temperature Rotary Seal
• Low-Friction PTFE Lip Seal
• OEM Process-Machinery Seal

The same dimensions alone do not guarantee interchangeability. The replacement must match the original PS-SEAL cross-section, PTFE grade, lip geometry, lip orientation, case construction, loading method, pressure direction, shaft requirements, installation direction, and operating conditions.

Food-contact or pharmaceutical suitability must be verified from the actual PTFE compound certification and complete seal construction. PTFE material alone does not automatically confirm regulatory compliance.

(Always verify dimensions, PTFE grade, double-lip orientation, sealing direction, case construction, shaft finish, shaft hardness, housing condition, installation depth, media compatibility, rotational speed, temperature, pressure, runout, and regulatory requirements before ordering.)
