Product description

The JF34 O-ring is a critical static seal that prevents hydraulic fluid from escaping through the cylinder gland threads. While it may seem like a simple component, a failure here can result in a significant mess and a loss of hydraulic pressure over time. SVI's replacement O-ring is made from high-nitrile rubber, chosen for its excellent resistance to petroleum-based hydraulic oils and its ability to maintain a seal under varying temperatures. This O-ring should be replaced whenever the cylinder gland is removed for service to ensure a leak-free reassembly. It is a precise fit for Rotary systems using the JF34 reference part.

Product highlights

• High-Nitrile Construction: Specifically selected for its compatibility with standard hydraulic oils and resistance to swelling.
• Consistent Cross-Section: Provides uniform pressure around the entire circumference of the gland for an even seal.
• Thermal Stability: Remains flexible and effective in both cold winter mornings and hot summer shop conditions.
• Static Seal Security: Prevents bypass at the gland-to-cylinder interface, ensuring total system integrity.
