Build-Your-Own Spools
Select the core and flanges you need to create a custom spool for storing twine, wire, rope, and chain. Flanges are threaded and have tabs for nonslip stacking.
Note: For each spool, order one core plus one pair of flanges.

FM-Approved Iron Pipe Fittings with Flanged Ends
FM approved, these fittings are suitable for use in fire-protection systems. All have flat-surface flanged ends that only mate to another same-size flat-surface flange, pump, or valve with a gasket (sold separately) to create an access point in a pipeline. Use them in noncorrosive areas.

- For Use With: Air, Natural Gas, Oil, Steam, Water
- Specifications Met: FM Approved, UL Listed, ASTM A126, ASTM B307, Fed. Spec. WW-F-406, ASME B16.1, ASME B1.20.1
- Pipe Nipples and Pipe: Use Schedule 40 steel
- Flanges: Use Class 150 steel

Expansion Joint Reducers with Flanged Ends
Connect different pipe sizes in your line while adding a point of flexibility between them. These expansion joints absorb movement between two connected pipes to reduce stress, vibration, and noise. Their flanged ends mate with same-size Class 150 flanges without the need for a gasket. Each flange is supported by a zinc-plated steel plate. The body of these expansion joints is reinforced with cord for added strength.
Your pipe system must be rigidly anchored on both sides of the expansion joint to control expansion or contraction of the line. When proper anchoring cannot be provided, limit rods (sold separately) are required.
