TOTO THP3051 – Frequently Asked Questions
1) What does the TOTO THP3051 adapter actually convert, 1/2 inch to 3/8 inch?
That's exactly what it does. The THP3051 is a compression adapter that takes a 1/2 inch connection down to 3/8 inch compression, so a supply stop or fitting sized at 1/2 inch can feed a 3/8 inch compression supply line.
2) I need to hook a 3/8 inch faucet supply line to a 1/2 inch stop under the sink. Is this the right part?
Yes, that is the situation the THP3051 is built for. It adapts the 1/2 inch side down to a 3/8 inch compression connection, which is the standard size on faucet and toilet supply risers. Note it is a compression adapter, so the 3/8 inch side takes a compression nut and ferrule, not a threaded flex hose end.
3) Is the TOTO THP3051 a strainer or an adapter? The name is confusing.
Despite the STRAINER wording in the TOTO part name, THP3051 is a compression adapter, 1/2 to 3/8 inch. If you are looking for a drain strainer or a filter screen, this is not that part.
4) What TOTO part number do I order for the 1/2 to 3/8 compression adapter?
Order TOTO THP3051. That is the manufacturer part number for the 3/8 inch compression adapter that steps a 1/2 inch connection down to 3/8 inch.
5) Will the THP3051 work with any brand of faucet or stop, or only TOTO?
It is a TOTO service part, but the connections are standard plumbing sizes: 1/2 inch on one side, 3/8 inch compression on the other. Anything matching those sizes mates with it. It is most often used on TOTO fixtures where a 3/8 inch compression supply has to meet a 1/2 inch connection.
