Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

The Billco Corporation 1/4 in. FPT Black Steel Cap is a rugged, lead-free solution for sealing off 1/4" pipe threads with a durable black finish. Crafted from solid steel, this cap delivers dependable protection against leaks and contamination in a compact, reliable design that stands up to everyday use.

Why this cap stands out

  • Lead-free construction—designed with safety in mind for a wide range of plumbing and mechanical applications.
  • 1/4 in. FPT thread—female pipe thread that cleanly mates with standard 1/4" male threads to cap off lines, ports, or outlets.
  • Durable black finish—a robust exterior that helps resist wear and makes identification easier in crowded utility spaces.
  • Solid steel build—provides reliable strength for capped lines in residential, commercial, and light industrial uses.
  • Maximum pressure up to 150 psi—suitable for many typical plumbing and HVAC systems without compromising safety.

Ideal use scenarios

  • Residential and commercial plumbing projects where a 1/4" line needs to be safely capped during construction, maintenance, or after repairs.
  • HVAC and sprinkler systems that require a secure, leak-free cap on unused ports.
  • Hydrostatic testing or temporary shutdowns where a reliable seal is essential to prevent contamination and debris entry.
  • Storage or transport of piping components to protect threads from damage and dirt.

Practical tips for installation and maintenance

  • Prepare the threads: ensure threads are clean and free of debris for a proper seal.
  • Seal the joint: apply PTFE thread sealant or appropriate pipe thread compound to enhance leak resistance, then thread the cap by hand and tighten with a wrench until snug.
  • Post-install checks: after pressurizing the system, inspect the cap area for any signs of leakage and re-tighten if necessary, avoiding overtightening that could damage threads.
  • Maintenance: periodically inspect caps in exposed or outdoor environments; replace if the finish shows significant wear or corrosion.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
