TOTO TH305SV104 – Frequently Asked Questions
1) Is the Toto TH305SV104 a rubber O-ring or a fiber washer?
Fiber, not rubber. The TH305SV104 U-packing set is a fiber washer set, which is a flat compression seal rather than an elastomeric O-ring seated in a groove. If the part you pulled out was a round-section rubber ring, this is not the replacement you want.
2) How many washers come in a Toto TH305SV104 U-packing set?
The TH305SV104 is sold as a bagged set of 10 fiber washers, so one order covers a batch of repairs rather than a single fixture. Useful for maintenance crews servicing multiple Toto fixtures on one trip.
3) What is a Toto U-packing washer actually used for?
It is a fiber sealing washer used as a fastener component in Toto plumbing and washroom fittings. Fiber washers compress against a mating face to seal a threaded joint, so they are replaced during a rebuild or whenever a joint weeps after service.
4) Can I reuse the old Toto fiber washer instead of buying the TH305SV104 set?
No. Fiber washers take a permanent set once they have been compressed, so a reused one is the usual cause of a joint that still seeps after a rebuild. Replace it with a fresh TH305SV104 washer any time the joint is broken open.
5) How do I order the right Toto U-packing set for a repair?
Order by the Toto part number TH305SV104. It ships in a single configuration, a 10-piece bag, so there is no size, finish, or handing choice to make on the order form.
