Product description
The Figure 1505 is a 15,000 psi union built for fracturing service, made in 3 in only, and designed to connect back to existing 3 in Figure 1502 iron.
Applications
Fracturing.
Construction and sealing
- Made in 3 in only.
- Backward connectable with 3 in Figure 1502 iron, so it goes into an existing spread without changing the rest of the line.
- A thread start marker on the nut removes cross-threading and cuts make-up time.
- Improvements in the critical areas of the union significantly extend its life.
- Available with butt weld ends.
Working pressure
15,000 psi (1,034 bar) cold working pressure, tested at 22,500 psi. A sour gas rating of 10,000 psi (690 bar), tested at 15,000 psi, is published for the same figure — tell us the service on your enquiry.
How a hammer union makes up
A hammer union is a three-piece connection. A male sub and a female sub carry the two line ends, and a wing nut turns on a thread cut into the male sub and pulls a shoulder on the female sub down onto the seat. The lugs standing proud of the nut are struck with a hammer to tighten it, which is where the name comes from — the joint is made up and broken out with a sledgehammer rather than a wrench, so a line can be rigged and stripped quickly in the field. The seal is made by the seat, not by the thread: the nut only supplies the load that holds the two seating faces together. That is why a union will leak from a scored seat or a perished seal long before the thread is at fault, and why a worn union is usually a sub or a seal replacement rather than a scrap part.
Specifying one
Four things fix a hammer union: the figure number, which sets the pressure class and decides what it will mate with; the service class, standard or sour gas; the end connection, threaded or butt weld; and the nominal size. Figure numbers are an industry series, so a union of the same figure and size from another maker will mate — but the pressure rating stamped on the union is what governs, not the figure number on its own. Send us the line specification and we will confirm the match before quoting.
Sizes and part numbers
Published in 3" with line pipe threaded and butt weld ends. The size table on this page states the working pressure for every size. Our source publishes no dimension table for this figure, so none is shown — ask us for a dimensioned drawing and we will get it from the mill rather than infer it.

Working pressure is the manufacturer’s published rating for the fitting itself. An assembly is limited by its lowest-rated component, so check it against the hose, the tube and the port you are mating to.
