Hammer Union
We put you first.
And keep you ahead.
Hammer Unions, also called Wing Unions, are quick makeup and break-out pipe and fitting connectors that have
been used in the oil industry since the early 1930s. The primary components in these connectors are a male sub with a
spherical contact surface, a female sub with external ACME
threads, and a wing nut with internal ACME threads to hold the
components together.
The 3" 1505 design
proof tested to outlast
current hammer union
technology at least 15
times longer in critical
fatigue applications.
FMC Technologies Weco® 3"
1505 Hammer Union has
several improvements over
the Weco® 3" 1502 Hammer
Union that address fatigue
and extend life significantly
in critical applications. A new
thread start marker on the nut eliminates cross-threading and
reduces make up time. The new component markings include
FMC Technologies figure number, size, pressure rating and
traceability for positive identification in the field.

The Weco® 3" 1505 Hammer Union is an
option when experiencing fatigue cracking in
Weco® 3"1502 applications.
FEATURES
Improved fatigue life due to significant design
improvements.
Eliminates conventional retainer segments, as well as
limit the durability of the product.
Use of proven TSi style seal with AE ring in an improved
configuration.
Positive seal retention in female sub to simplify make-up
and minimize errors.
Entirely inter-connectable with current FMC Technologies

NOTES:
* Do not suspend loads on service lines using wing union
connections. Externally applied bending or tensile loads
are additive to the loads already induced by internal
pressure. Externally applied loads can result in an overstress condition leading to catastrophic failure. If externally
applied loads are to be applied, consult factory for
limitations.
* FMC Technologies cannot anticipate all of the situations
a user may encounter while installing and using FMC
products. Therefore, the user of FMC products MUST
know and follow all applicable industry specifications
and practices on the safe installation and use of these
products. For additional safety information, refer to FMC
Technologies website at www.fmctechnologies.com/
fluidcontrol or contact FMC Technologies at 800/772-8582.
NOTES:
* Use of non-FMC manufactured parts in FMC Technologies
products may result in death, personal injury or property
damage. The use of non-FMC parts voids all design, type,
case, test and quality approvals by third-party certifying
authorities and may void product warranty.
* Never assemble wing union components together that are
not positively identified as to the manufacturer, service and
pressure rating. Failure to do so can result in a connection
that may fail under pressure, which can lead to death,
serious personal injury and severe property damage.

3" 1502 Seal
The Weco® 3" 1505 seal features an anti extrusion ring.
The 3" 1505 seal uses a barb retention, versus the
internal groove on traditional 3" 1502 female seal
pocket.
TESTING

All combinations of the Weco® 3" 1505 had higher burst
pressure than the 3" 1502. All combinations of mixed connections had failure pressure higher than 3" 1502 but lower
than 3" 1505.
