37R Rigid Rocker Lug Female to Male Adapter (ACE AA137)
There are various ways to utilize this adapter, such as a reducer, increaser, or changing from one type of thread to another.
We offer many different thread choices to accommodate our customers throughout the USA. We maintain a card file in our office with thread types used by various cities throughout the USA.
Our standard threads are NST (NH). They will typically ship quicker, and NSPH can be supplied for no additional charge. If your thread type is not shown below, please call us to discuss your requirements.
National Standard Thread (NST), also known as National Hose thread (NH). It is the most common type of fire hose coupling used in the United States.
National Pipe Straight Hose (NPSH), also known as Iron Pipe Thread (IPT). It has the same TPI as NPT, but the thread does not taper. NPSH is a straight thread and seals by a gasket in the female coupling, which allows for a swivel.
Tapered Pipe Thread (NPT) Only available on the rigid side of the adapter, cannot be furnished on the swivel side. When NPT is requested, it will be furnished to ANSI B2-1968. NPT requires additional material by the Government Specifications and calls for a longer thread, therefore, causing the added thread charge.
We also offer custom laser engraving of your adapters for an additional charge. If you require this option, please selectthat optionand type in the boxthe name or initials you want laser engraved. The price for laser engraving is for up to a maximum of 12 letters/numbers, and the size of your adapter limits us on how many letters/numbers we can engrave. Laser engraved adapters are not subject to cancellation or return.
