One measurement on your description says 1.25". Looking at the picture the hole is 5/8" so what is the 1.25"? This looks like my seal but nothing on my 5/8" seal measures 1.75". Looking at the proportions on the picture nothing looks 1.75"
Reply
The 1.25" measurement refers to the outside diameter of the shaft seal.

Is there any thing special when installing this seal?

Looking for replacement seal and orings for Optiflo Plastic Pump Model CPT-N!-1.5 part # 454545 & 357255

Hi Mickey, You would require the shaft seal on this page for the Optiflo pump. For the o-rings you would need a quantity of two of the 357 O-ring and a quantity of one of the 223 O-ring.

I disconnect my pool pump. Next I disassembled I the pump revealing the impeller. Next I removed the impeller exposing the shaft seal. After removing the shaft seal I installed the new replacement seal and the reassembled the pump. Finally I reconnected the pump to the pool and ran it. No leaks!

I use a 5/8 socket to push/tap the old seal out of pump. I also apply thin coat of seal lubricant on rubber collar before inserting/seating it in pump. Keeps rubber from binding.

Remove and discard used impeller. Remove and replace wet end housing seal. Remove rust from motor shaft using emery cloth and grease lightly. Install wet end housing careful not to touch ceramic surfaces. Screw impeller not to tight as motor spin direction will keep it tight. Reassemble pump using new o rings and Teflon lube such as Aladdin magic lube

I wanted to have a set of bearings and a seal on hand for replacement during my next regular service of the hot tub.
Being over 25 years old, I had some difficulty verifying the necessary parts, and got excellent guidance online from INYO pools. Ordered parts which arrived in days and the following weekend, drained the tub for cleaning and a water change.
I wrestled the pump out and disassembled and cleaned the motor. Replaced the bearings and put in a fresh seal as always.
Very pleased to have the correct parts on hand for the job, and it went as smoothly as one could hope.
Thank you INYO pools, I will be back next time I need anything and will suggest you to anyone who needs pool and spa parts and supplies.

An absolute must to replace this every spring, or when doing a rebuild. I prefer to pull the pump over winter to avoid the nasty winter elements.

(5 out of 5 stars) Replace Shaft Seal FIRST before o-rings
Reviewed By: Inyo Customer ()
Easy to install with no problems. I definitely will be on the alert to replace the shaft seal whenever I see any water under the pump motor. I won't waste time replacing o-rings first. The part is not that expensive and it is most important to protect the more valuable motor from water damage.

Took my pump apart to find a broken seal. Searched on the site and found this replacement. When I received it, I put the pump back together and the seal has performed as expected. Definitely worth the money and great quality.

(4 out of 5 stars) Difficult to tell if you're ordering the right part-all look similar.
Reviewed By: Joe N. from El Paso, TX ()
Pros: Good price and arrived quickly.
Cons: Somewhat difficult to tell if you are ordering the right part. Best to call the rep. Wish they better install instructions. Instructions just say "install the same way the old one was installed"
I had the benefit of having the old gasket and after reviewing several pictures on the helpful Inyo website I felt fairly confident I ordered the correct part. Installation Tip: the rubber gasket parts are installed on opposite ends of each other - i.e. the white ceramic and the black graphite parts make contact and face each other.

(5 out of 5 stars) Great pool pump seal
Reviewed By: Home handyman from Starkville, MS ()
Pros: Great quality, clear instructions
Cons: None
The seal arrived as scheduled and was of good quality. The included instructions were detailed, and had information that was critical for proper installation. The instructions also included tips on how to avoid premature failure. I installed the seal at the same time that I replaced the old pump motor with a new energy efficient motor from INYOpools. Both are working well, without problems.
