Product details
The Jandy R0412700 is the o-ring for the 2 inch union, the seal that sits in the union face and holds the joint watertight. It is the genuine Jandy part.
Where it is used
Jandy uses 2 inch unions throughout the equipment pad, and this is the o-ring listed for that connection, including the 2 inch LX unions at an AquaPure cell. It is the part that comes out when a union is opened for winterizing or for cleaning a cell, and the part most likely to be pinched or nicked on the way back together.
The mistake to avoid
When a union drips, the instinct is to lean on the collar. That does not work. A union seals on the o-ring, not on clamping force, and cranking the collar down distorts the faces and can crack the nut. If it weeps after hand tightening, the o-ring is done.
Fitting
Clean the groove, check that no grit is trapped in it, and put a thin film of silicone based lubricant on the new o-ring before assembly. It seats more evenly and comes apart far more easily next time.
