Your Navien should come with a bag of these o-rings taped to the right hand side of your tankless but if gone buy this set. Has all the O-Rings you need for maintenance.

There were at least 5-6 different metric sizes or all of the various o-ring requirements inside the unit.

Comprehensive o ring kit to have on hand, just missing the dirt trap o ring which is an important one to have, which I had to order separately.

Does not contain the o-ring for the condensate trap. Not a complete set.

Like the fact I didn't need to create a list and then shop individually for these seals. The heaters will leak sooner of later, best to have these on hand .

This is the exact kit I needed to replace several old orings for my tankless water heater. I gave a 4 and not 5 star simply because the labelling doesn't match the part numbers in manual and could have used a few more of each size, but definitely worth it. Fixed up drip leaks I had perfectly

Ordered this kit for my Navien NP-240a. Not enough o rings to do the job and a few that didn't fit. Luckily I had an Oring kit from Princess auto that had what I needed to finish the job. Wouldn't bother buying again.

The product information and specification from the seller are misleading and false. The item is VERY EXPENSIVE. DON'T BUY. I bought the o-rings to repair my leaking Navien tankless heater dirt trap. But the rings never worked even though very expensive. I bought a cheaper one from Princess Auto which had every type of O-rings at less than half the price I paid for this.
