Hexagonal 316 stainless steel reducing bushing coupling with male and female NPT threads

Value Brand

Value Brand 1RTU7 316 Stainless Steel Hex Reducing Bushing coupling

SKU CH-2BWT-6R830

Hex reducing bushing connects 1-1/4" male NPT to 3/4" female NPT with 316 stainless steel rated to 3000 psi at 100°F

  • 316 stainless steel resists corrosion in harsh environments
  • Hex flats allow secure tightening with a standard wrench
  • Rated 3000 psi at 100°F for high-pressure systems
  • Conforms to ASTM-A-182 and ASME B16.11 standards
  • Male NPT 11 1/2 TPI to Female NPT 14 TPI thread transition

Stainless Steel Reducing Bushing

This 316 stainless steel hex reducing bushing connects a 3/4 inch female NPT opening to a 1-1/4 inch male NPT thread. It suits plumbing and industrial systems that require a durable, corrosion-resistant transition between dissimilar pipe sizes. The fitting meets ASTM A182 material requirements and ASME B16.11 dimensional standards for reliable service.

Upgrading From Lower-Grade Fittings

Installers replace carbon steel or brass bushings when the media or environment demands superior chemical resistance and higher pressure integrity. The jump is worth it when operating pressures approach 3000 psi at 100°F or when 316 alloy compatibility is specified for the process fluid. Threads conform to ANSI/ASME B1.20.1 for consistent sealing.

Sustained High-Temperature Pressure Performance

The fitting maintains a 2500 psi rating at 350°F, allowing continuous operation in hot fluid or steam lines without derating. The hexagonal profile ensures secure wrench engagement during assembly, preserving seal integrity through thermal cycling. California Proposition 65 warnings apply for chemical exposure.

Questions about this item

What size wrench fits the hex flats on this 316 stainless steel reducing bushing?

The fitting has a hexagonal outer profile designed for tightening with a standard wrench on the hex flats.

How do I seal the Male NPT and Female NPT threads correctly during installation?

Apply PTFE tape or pipe-thread sealant on the male threads only, then tighten to the recommended turns past finger-tight to avoid cracking the 316 stainless steel body.

When should I replace this Class 3000 fitting in a high-temperature system?

Inspect regularly for thread deformation or corrosion; replace if the joint sees sustained temperatures above 350°F or pressures exceeding 2500 psi at that temperature.
