Specified Fittings

What Specified Fittings does

Specified Fittings is a privately-held pipe fittings fabricator founded in 1997 and headquartered in Bellingham, Washington. According to firmographic data, the company operates with 11-50 employees and specializes in custom fabrication of fittings across three thermoplastic material families: HDPE (high-density polyethylene), PVC (polyvinyl chloride), and CPVC (chlorinated polyvinyl chloride).

The company's core offering is custom-fabricated pipe fittings rather than standardized catalog products, addressing applications in water/wastewater infrastructure, chemical processing, plumbing, and industrial fluid handling where project-specific dimensions, pressure ratings, or material compatibility requirements must be met. Multi-material capability across HDPE, PVC, and CPVC allows the company to serve specifications covering corrosive chemical service, potable water, and higher-temperature hot-water/industrial lines within a single vendor relationship. The website domain (specifiedfittings.com) and the company's name emphasize a "specification-grade" positioning, consistent with serving engineers, contractors, and procurement teams working from technical drawings rather than off-the-shelf buyers.

The business model is consistent with a small-batch, project-driven industrial fabricator: revenue derives from custom fabrication orders priced per job on the basis of material, dimensions, tolerances, and quantity rather than subscription or volume licensing. Go-to-market appears to be direct/specifier-driven (engineers, contractors, distributors) with no digital channel or marketing motion reported in the available data. The only sourced capital relationship is a 2014 funding event involving NorthStar Capital; no pricing, customer, or contract data is publicly available, and the harcofittings.com verification page yielded no substantive company content.
