Q&A
Frequently Asked Questions
Q:
Which Microline housings use the S3069 O-ring?
A:
The S3069 is used on compatible 2-3/4-inch white Microline housings, including approved CTA-14D, CTA-14S, TFC-25D, TFC-25S, TFC-300, TFC-335, TFC-400, TFC-400-ESP and TFC-435 systems.
Q:
Is the S3069 for the older or newer Microline housing?
A:
It is commonly identified as the O-ring for the newer-style white housing. Housing revisions can use different seals, so compare the part number and housing style rather than ordering by diameter alone.
Q:
When should I replace the S3069 O-ring?
A:
Replace it if it is flattened, cracked, cut, swollen or stretched, or if the housing seeps after being correctly tightened. Keeping a spare on hand prevents a routine filter change from being delayed by a damaged seal.
Q:
Should I lubricate the Microline housing O-ring?
A:
Apply only a very light film of food-grade silicone lubricant. Petroleum grease can damage many elastomers, and excess lubricant can attract grit that interferes with the seal.
Q:
How do I install the S3069 without causing a leak?
A:
Shut off water and relieve pressure, remove the old seal, wipe the groove and mating surfaces, then seat the S3069 evenly without twisting it. Hand-tighten the housing and check for leaks after pressure is restored.
Q:
Will tightening the housing more stop an O-ring leak?
A:
Not necessarily. Overtightening can distort the seal or make future service difficult. If a correctly seated housing leaks, inspect the S3069 and sealing surfaces for damage or debris before applying more force.
