Pipe Cap 1/4" FNPT Malleable Iron

This Value Brand malleable iron cap terminates a 1/4 inch female NPT pipe end in plumbing systems. The Class 150 fitting handles pressures suited to standard water, air and gas lines. It is rated for continuous service from -20 degrees to 366 degrees Fahrenheit. The round cap threads directly onto male NPT pipe without additional sealing components.

Installers closing 1/4 inch NPT lines

Plumbers and maintenance technicians use this cap to seal unused ports on valves, manifolds or equipment during assembly or repair. The malleable iron construction resists mechanical shock and vibration in industrial settings. Installers who require a stainless steel or brass fitting for corrosion resistance should select a different material. Systems demanding a higher pressure class than 150 need an alternative fitting.

Class 150 pressure rating

The 150 Class designation defines the maximum allowable pressure at the rated temperature range. This single specification determines whether the cap is suitable for the intended service conditions. Verify the system design pressure against this rating before installation. California Proposition 65 warnings apply to this product.

Questions about this item

Will the malleable iron cap need any thread sealant reapplied during its service life?

The cap ships without pre-applied thread sealant, so any future disassembly and reassembly will require fresh sealant on the 1/4 inch FNPT threads.

What temperature limit is reached first when the fitting runs continuously at its upper rating?

The 366 degrees Fahrenheit maximum operating temperature is the limiting factor before the Class 150 pressure rating becomes a concern.

How hot does the iron body get when the system operates at the top of the rated range all day?

At the 366 degrees Fahrenheit limit the cap itself will reach that temperature, so insulation or guarding is needed to prevent burns.
