Product details

Jandy R0446400 is the tail piece o-ring, supplied as a set of two. It seals the union tail pieces on Jandy pumps.

Where it sits

Every Jandy pump connects to the plumbing through unions. The tail piece threads into the pipe, the nut pulls it up against the pump port, and this o-ring is the only thing making that joint watertight. Because there is one at the suction side and one at the discharge, Jandy sells the o-ring in pairs.

When to change it

A union that weeps or drips at the nut is almost always an o-ring problem, not a tightness problem. Once the rubber has hardened, cracked or taken a permanent flat spot, tightening the nut harder just distorts it further. Back the union off, pull the old o-ring, wipe the groove clean, fit the new one with a pool grade lubricant and hand tighten the nut.

Fitment

This o-ring is listed for the Jandy Stealth series pumps, the Jandy ePump variable speed pumps and the Jandy WaterFall series pumps.

Questions and answers

What people ask about this product, answered by our pool techs.

How many o-rings come in the set?
Two, which is enough to do both unions on a pump at once.
Which pumps use this o-ring?
It is listed for the Jandy Stealth series, the Jandy ePump variable speed pumps and the Jandy WaterFall series.
My union drips even after I tighten it. Is this the fix?
Usually. Once a union o-ring hardens or takes a set, more torque on the nut will not seal it and often makes the leak worse. A fresh o-ring is the correct repair.
Should I lubricate them?
A pool grade o-ring lubricant helps the o-ring seat evenly and keeps it from pinching or rolling as the union is tightened.
