FIG 402 is available only in a 2-inch nominal size and is identified by a black nut, black connecting parts, and an NBR seal ring. These features can help with visual identification during receiving or replacement, but the figure designation should still be verified before ordering or installation.
For additional identification guidance, see the hammer union markings guide.
FIG 402 and FIG 400 are different hammer union configurations. FIG 402 is available in a 2-inch size with an NBR seal ring, black nut, and black connecting parts. FIG 400 is available in 2-inch, 3-inch, and 4-inch sizes and uses a thick-wall design with ring-shaped and tapered sealing.
Specifications are figure-specific, so FIG 400 pressure ratings, dimensions, weights, and material information should not be applied to FIG 402. For FIG 400 specifications, see the FIG 400 Hammer Union page. For FIG 402 project-specific technical data, confirm the required values with AlienFrac before ordering.
For a FIG 402 quotation, provide the figure number, 2-inch nominal size, required quantity, and any required project documentation. If pressure rating, dimensions, material certification, connection details, inspection records, or drawings are required, include these requirements with the RFQ.
For general connection terminology, see the hammer union connection types guide. Confirm the required FIG 402 connection configuration with AlienFrac before ordering.
