SPNS
(Step Seal with PTFE and O-Ring Energizer) is a
static hydraulic rod seal
installed in gland housings to prevent fluid leakage during rod reciprocation. Its design includes:
PTFE Slip Ring: Provides ultra-low friction, chemical resistance, and thermal stability.
Elastomeric Expansion Ring (O-Ring): Compensates for PTFE
’
s rigidity by supplying elasticity and initial sealing force.
Bronze-Filled PTFE: Enhances wear resistance and reduces extrusion risk under high pressure.
This two-component system ensures reliable sealing in applications where traditional polyurethane seals fail.
SPNS seals excel in environments where low friction, corrosion resistance, and media compatibility are critical:
Hydraulic Cylinders in marine or offshore equipment (exposed to saltwater/oil emulsions).
Industrial Machinery handling water-glycol or fire-resistant hydraulic fluids.
Mining Equipment operating in abrasive, high-pressure conditions.
Chemical Processing Systems requiring resistance to aggressive media.
Advantages:
1.Chemical resistance
2. Heat resistance
3. Low friction
4. Has good oil return property
5. Easy installation
6. Longevity
7. High-pressure resistance
The
PTFE SPNS Step Seal
is a game-changer for hydraulic systems demanding low friction, chemical resistance, and reliability in extreme conditions. By pairing PTFE
’
s unmatched material properties with a precision-engineered O-ring energizer, this seal solves the limitations of polyurethane and traditional elastomers. Whether you’re battling abrasive media, high pressure, or corrosive environments, the SPNS seal delivers unmatched performance and longevity.
