AppliaFit's Bulkhead Replacement Kit is a direct-fit repair set designed to replace the bulkhead assembly on Pentair 154714 Triton II fiberglass sand filters, restoring a watertight connection and reliable filtration performance.

If your Triton II sand filter shows leaks or has worn seals around the bulkhead, this single-kit replacement supplies the parts needed to refresh the connection without replacing the entire tank. The kit fits a wide range of Triton II models (TR40, TR50, TR60, TR100, TR140 and their HD/C/C-3 variants) and uses heavy-duty materials intended for long service life. Packaging may vary, and model names are referenced solely to indicate compatibility.

How will this bulkhead kit stop leaks and restore filter function?

Replacing a worn or damaged bulkhead assembly removes common sources of seepage and pressure loss in sand filters. New sealing faces and O-rings create a tight interface between the tank and plumbing, reducing drips and preventing air entry that can impair pump performance.

• Includes replacement components sized to match Pentair 154714 mounting points.
• New O-rings restore compression sealing around threaded fittings.
• Durable construction resists deformation under normal filter pressures.

Which Triton II models will this kit fit and how do I confirm compatibility?

The kit is compatible with Triton II fiberglass sand filter models TR40, TR50, TR60, TR100 and TR140 plus their TR100HD, TR100C, TR140C, TR100C-3 and TR140C-3 variants. Confirm fit by matching your filter's part number or the original bulkhead part number listed for Pentair 154714.

• Cross-references include common alternate part numbers for quick verification.
• Fitment is for the bulkhead assembly location on the filter tank.
• If in doubt, compare the physical shape and thread size with your existing bulkhead.

What materials and quality features does the AppliaFit kit offer?

The kit is manufactured from heavy-duty materials selected for longevity in pool and spa environments. While not intended to be a manufacturer original, the components are engineered to resist compression set and chemical degradation typical around sand filter plumbing.

• Reinforced plastics and elastomers for chemical and pressure resistance.
• O-rings sized to maintain a reliable seal under normal operating conditions.
• Precision-molded parts to match mounting tolerances and reduce installation issues.

How difficult is installation and what tools are needed?

Installation is straightforward for anyone familiar with basic pool equipment maintenance; it generally requires removing the old bulkhead, cleaning mating surfaces, and installing the new pieces with proper torque. Turn off and bleed the system before starting, and inspect the mating surface for cracks before installing the replacement.

• Common tools: adjustable wrench, screwdriver, utility knife to remove old sealant.
• Recommended: light lubricant for O-rings and cloth for surface cleaning.
• Typical time: 20–45 minutes depending on accessibility and condition of existing parts.
