Q&A
Q:
What does the H-118 O-ring fit?
A:
The catalog lists H-118 for Omnipure Q-Series applications including PT3000 CTA 18 GPD; PT3000 TFC 36 and 50 GPD; PT4000 TFC 36, 50, and 75 GPD; EZ-450; and EasyPur EZ-575. Match the H-118 part number and the large-seal position before ordering.
Q:
What are the dimensions of the H-118?
A:
The listed size is approximately 7/8-inch ID, 1-1/16-inch OD, with a 3/32-inch cross section. The product name's general size reference should not replace checking the precise ID, OD, and cross section.
Q:
Can this O-ring help stop a leak at the Q-Series head?
A:
Yes, if the leak is caused by a worn, cut, flattened, missing, or displaced seal. Inspect the head and cartridge for cracks or connection damage as well.
Q:
Should I lubricate the O-ring before installation?
A:
A very light coating of food-grade silicone lubricant can help the seal seat without twisting. Do not use petroleum jelly, which can damage some elastomers.
Q:
How tight should the filter be after replacing the O-ring?
A:
Install the seal in its groove, make sure it is not pinched, and reconnect the cartridge according to Omnipure instructions. Overtightening does not correct a mis-seated seal.
Q:
When should the H-118 O-ring be replaced?
A:
Replace it whenever it shows cuts, flattening, stretching, brittleness, or leakage. Keeping a spare with replacement filters can prevent an interrupted filter change.
