ATRACYPART Hot Tub Filter Standpipe Caps 6-Piece Set, 3.5" (1 Grey + 5 White) — Screw-On Debris Seal for Hot Spring Spas

Replacement standpipe caps for Hot Spring spas that secure filters, prevent debris entry, and fit the Freshwater AG+ 71325 system.

Keep your Hot Spring or compatible spa running smoothly with this 6-piece cap set from ATRACYPART. The kit includes one grey cap tailored for the grey standpipe that houses the Freshwater AG+ Continuous Silver Ion 71325 system and five white caps for the remaining standpipes. These caps screw onto the top of the filter standpipes to hold filters vertically and block dirt, small objects, and buildup from entering the plumbing and pump area.

How will these caps protect my spa pump and plumbing?

Standpipe caps form a tight barrier at the top of the filter standpipe, stopping larger debris and foreign objects from falling into the suction pathway. That reduces the risk of clogs, impeller damage, and pressure-related wear on the pump.

• Screw-on design creates a reliable seal to keep out hair, leaves, and loose particles.
• Maintains filter vertical position to ensure correct flow and filtration efficiency.
• Prevents foreign objects from entering the pump housing and plumbing lines.

Will these caps fit my Hot Spring spa model?

Yes — the set is made to match the common 3-1/2 inch standpipe caps used across Hot Spring hot tub lines and compatible models. The grey cap specifically fits the grey standpipe used with the Freshwater AG+ 71325 system, while the white caps fit the remaining white standpipes.

• Compatible with Hot Spring families such as Highlife, Hot Spot, Limelight, Tiger River, and Caldera.
• Designed for the standard 3-1/2" standpipe diameter used in these systems.
• Works with existing Hot Spring spa filtration housings and replacement filters.

How easy is installation and maintenance?

Installation is straightforward: line up the cap threads and screw onto the standpipe by hand until snug. Periodic inspection and simple removal for cleaning are all that’s required to keep the caps performing well.

• No tools are required for most installs — hand-tighten until secure.
• Remove, rinse, and inspect caps when servicing filters for simple upkeep.
• Replacement is fast: swap a worn cap in minutes to restore proper filter positioning.

What makes this ATRACYPART kit the right choice over single replacements?

Buying a multi-piece kit ensures you have matching caps for each standpipe, reducing the chance of mismatched colors or lost parts. The included grey cap covers the special Freshwater AG+ standpipe, so the set is ready for complete filter-top renewal.

• Six caps provide full coverage for typical 5-standpipe setups plus the AG+ grey cap.
• Consistent fit and finish across all pieces avoids uneven sealing or loose filters.
• Backed by a 12-month warranty for added purchase confidence.

Who is this for? If you own a Hot Spring spa or a compatible tub using 3-1/2" standpipes — especially systems using the Freshwater AG+ 71325 silver-ion insert — this ATRACYPART 6-piece cap kit is for you. It’s ideal for owners replacing missing or damaged caps, shop technicians stocking replacement parts, and anyone maintaining clean, trouble-free circulation in their spa. The set keeps filters correctly positioned, protects pumps and plumbing from debris, and offers an easy, cost-effective way to restore proper filtration function.
