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 Hammer Union is an option when experiencing fatigue cracking in Weco 3"1502 applications. BENEFITS 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 Weco 3" 1502 iron. FEATURES Interconnectable is fully inter-connectable with current FMC's 3" 1502 iron. Improved Male Sub-to-Female Sub Contact Surface 3" 1505 has larger face-to-face contact diameter than the 3" 1502, which has a spherical surface-to-chamfer line contact. Larger contact diameter of the 3" 1505 improves bending capacity.

FEATURE OVERVIEW Significant improvements in select high critical areas of the current FMC Technologies Weco 3" 1502 iron. Improvements particularly address fatigue and extend life significantly in critical applications. design proof tested to outlast current hammer union technology at least 15 times longer in fatigue applications. Thread start marker on nut eliminates cross-threading and reduces make up time. Component markings include FMC Technologies figure number, size, pressure rating and traceability for positive identification in the field. Eliminates conventional retainer segments, as well as limits 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 Weco 3" 1502 iron.

LOAD SEGMENTS 1505 1505 1502 1505 Male to 1502 Female Male to 1505 Female Angle of the shoulder changed to reduce stress concentration. The Weco 3"1505 port plug on the nut has positive retention groove to keep the port plug securely in place. 3" 1505 load segments are axially symmetric, so that they can be loaded into loading port in nut either way. Segments * 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. * 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
NUT WECO 3" 1505 NUT Weco 3" 1502 3" 1505 nut has same markings as that of the 3" 1502, but the batch number was moved as a result of the lugs being moved away from face of nut. Lugs centered to improve fatigue characteristics. The 3" 1505 nut's external thread start marker and thread start feature eliminates cross-threading and significantly reduce make up time. No special marking on 3" 1505 sub ends themselves, but their uniqueness will allow it to stand apart from 3" 1502 sub ends. FEMALE SUB SEAL No partial threads on female sub end. Have at least 4 full threads of engagement on Weco 3" 1505 compared with 3 full threads of engagement on 3" 1502. Full threaded start on 3" 1505 female sub end and lead in feature on 3" 1505 nut allow for easy thread start every time. 3" 1505 Seal 3" 1502 Seal The 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. 4
