Description
R154492 – Bulkhead connection o-ring for sand filter Triton (pack of 2) – (PENTAIR) – Origin : EU
The R154492 bulkhead connection o-ring for sand filter Triton (pack of 2) is the original sealing set for Pentair Triton sand filter bulkhead fittings. These o-rings sit between the tank wall and the bulkhead connection, ensuring a watertight and airtight seal so the filter can work at normal operating pressure without leaks.
Function of the Triton bulkhead connection o-rings
In a Pentair Triton sand filter, the bulkhead connection passes through the filter shell to connect the internal collector assembly to the external pipework or valve. The R154492 o-rings are compressed around this passage, creating a reliable seal between the tank body and the bulkhead fitting. Good o-rings are essential to prevent water seepage around the connection and to keep the installation safe and dry in the technical room.
Compatibility and application
The R154492 bulkhead connection o-ring pack is designed specifically for selected Pentair Triton sand filters that use this type of bulkhead connection. The dimensions and rubber compound match the original factory parts so they fit directly in the dedicated groove without modification.
- Original Pentair o-ring set for Triton sand filter bulkhead connections.
- Pack of two seals, usually covering both sides of one bulkhead or two separate fittings.
- Suitable for use in chlorinated and salt water pool systems.
- Recommended whenever bulkhead fittings are dismantled or the tank is refurbished.
When to replace the bulkhead o-rings
Bulkhead o-rings work under constant pressure and are exposed to temperature changes and pool chemicals. Over time they lose elasticity and can no longer guarantee a perfect seal, which may lead to small leaks around the filter connections.
- Visible cracks, cuts or flattened areas on the existing o-rings.
- Moisture, rust marks or white scale around the bulkhead area on the outside of the tank.
- Water seeping from the connection when the filter is running or after starting the pump.
- Any major service where the bulkhead fitting is removed from the Triton filter shell.
Installation and maintenance tips
Replacing the R154492 bulkhead connection o-rings is normally done during filter maintenance or when solving leaks around the tank connections. Always depressurise the system and isolate the filter before starting.
- Switch off the pump, close valves and release pressure from the filter using the air relief or drain point.
- Disassemble the bulkhead connection carefully, noting the position of each part.
- Remove the old o-rings and clean the sealing surfaces on the tank and fitting, removing scale and dirt.
- Fit the new o-rings in their grooves, making sure they lie flat and are not twisted.
- Lightly lubricate the seals with a silicone based lubricant suitable for pool o-rings if recommended.
- Reassemble the bulkhead fitting and tighten evenly so the o-rings compress uniformly around the opening.
After reassembly, restart the system and inspect the bulkhead area at working pressure to confirm that the connection remains completely dry.
Good practice for a reliable Triton filter installation
Using original Pentair R154492 o-rings and following good maintenance practice helps extend the service life of the sand filter and associated fittings.
- Check the bulkhead area periodically for early signs of seepage or deposits.
- Keep water balance within the recommended ranges to reduce stress on rubber components.
- Avoid overtightening fittings, which can deform o-rings and tank connections.
- Replace seals whenever the filter is opened for major internal work or media changes.
With new R154492 bulkhead connection o-rings fitted correctly, Pentair Triton sand filters maintain a secure, leak free connection through the tank wall, supporting safe and efficient filtration over many seasons.
