FIG 1502 HAMMER UNION

AlienFrac FIG 1502 hammer unions are designed for high-pressure oilfield connections. The catalogue specifies a replaceable resilient nitrile-butadiene rubber seal ring and a robust wall-thickness design. FIG 1502 is rated at 15,000 PSI NSCWP with a 22,500 PSI test pressure. Available catalogue sizes are 1½ in, 2 in and 3 in, with a blue nut and red parts for visual identification. The listed applications are cementing, fracturing, acidizing, testing, and choke & kill lines.

FIG 1502 Key Specifications

  • Working pressure: 15,000 PSI NSCWP
  • Test pressure: 22,500 PSI
  • Nominal sizes: 1½ in, 2 in, and 3 in
  • Seal: replaceable resilient nitrile-butadiene rubber seal ring
  • Color identification: blue nut and red parts
  • Catalogue material code: SF for nut and part
  • Applications: cementing, fracturing, acidizing, testing, and choke & kill lines
  • Butt-weld note: Butt weld Sch. XXH is desired

Pressure and color are quick identification cues, but they are not a substitute for checking the figure number, nominal size, markings, end requirement, and service conditions. For broader selection context, review the hammer union pressure ratings and color codes guide before confirming an order.

Seal Design for High-Pressure Service

The FIG 1502 union features a replaceable nitrile-butadiene rubber (NBR) seal ring and a robust wall design for high-pressure service. Seal condition, correct assembly, and application requirements should be verified before use. Sour-service suitability, material grade, certification, and interchangeability with other manufacturers’ unions should be confirmed separately rather than inferred from the FIG 1502 designation alone.

Typical FIG 1502 Applications

  • Cementing: Suitable for cementing service. For related hose-side selection, review the cement hose range and confirm the complete assembly requirements.
  • Fracturing: Used in high-pressure fracturing service.
  • Acidizing: Used in acidizing service; confirm project-specific media compatibility and material requirements before ordering.
  • Testing: Suitable for testing service within the specified system pressure and operating requirements.
  • Choke & kill lines: Used in choke and kill line service. Review API 16C choke and kill hose options separately and verify the required end connection and system rating.

Connection and Installation Notes

FIG 1502 may also be used in a pressureless seal connection, with butt-weld Sch. XXH specified as the preferred arrangement. Confirm the end configuration, mating components, and installation requirements for the actual system before purchase.

For an overview of threaded, butt-weld, socket-weld, and specialty arrangements across the wider product category, see the hammer union connection types guide.

How to Specify a FIG 1502 Hammer Union?

To prepare a quotation, provide:

  • Nominal pipe size: 1½ in, 2 in, or 3 in
  • FIG 1502 requirement and 15,000 PSI NSCWP rating
  • Required end or connection configuration
  • Application or service conditions
  • Quantity
  • Required inspection, marking, and documentation details
  • Project-specific dimensional or packaging requirements

If you are checking an existing component, record the figure number, nominal size, pressure rating, manufacturer, and heat or lot details rather than relying on color alone. The field guide to reading hammer union markings explains what information to record before requesting a replacement.

FIG 1502 or FIG 602?

Do not select a hammer union by appearance or nominal size alone. FIG 1502 and FIG 602 are intended for different pressure and service requirements. Use the dedicated FIG 602 vs FIG 1502 comparison to review the key selection factors, then return to this product page when FIG 1502 is the specified figure.

FAQ

What is a FIG 1502 hammer union used for?

FIG 1502 is used for cementing, fracturing, acidizing, testing, and choke & kill line applications.

The FIG 1502 hammer union is rated at 15,000 PSI NSCWP, with a test pressure of 22,500 PSI.

The listed nominal pipe sizes are 1½ in, 2 in, and 3 in. Refer to the dimension table for the corresponding inch and millimetre values.

FIG 1502 is identified by a blue nut and red parts. Color should only be used as a quick identification cue; always verify the figure number, nominal size, pressure rating, and product markings.

The FIG 1502 union uses a replaceable resilient nitrile-butadiene rubber (NBR) seal ring.
