Key Features

Superior Brass Situate Innovation: The 341 show consolidates a brass situate ring that makes a soft-to-hard metal seal. This plan beats standard iron-to-iron contact, particularly in high-pressure steam applications.

Space-Saving Plan: The male-female setup combines union and areola capacities into one component. You spare establishment space and diminish gathering time.

High-Vibration Resistance: The brass situate misshapes somewhat beneath weight, keeping up tight seals indeed in situations with critical vibration or warm cycling.

Easy Upkeep Get to: You can evacuate gear without destroying whole pipe runs. This include drastically diminishes upkeep labor costs.

Corrosion-Resistant Wrap up: The dark coating gives great assurance for indoor gas, steam, and oil applications where galvanization isn't required.

Materials and Surface Treatment

Our pliable press development takes after strict ASTM A197 guidelines, guaranteeing reliable quality and execution. The fabricating prepare incorporates controlled cooling that makes the perfect adjust of quality and ductility.

The dark surface treatment comprises of a specialized polish or oil wrap up. This coating gives erosion resistance amid capacity and benefit in non-corrosive situations. The wrap up too makes a difference recognize gas lines from water lines in mechanical installations.

Application Areas

Industrial Steam Frameworks: Your steam trap gatherings advantage from the 341's warm cycling resistance. The brass situate keeps up judgment through rehashed warming and cooling cycles.

Natural Gas Foundation: Gas meter bars and controller stations depend on these fittings for secure, leak-free associations. The dark wrap up meets industry benchmarks for gas line identification.

Hydronic Warming Frameworks: Commercial evaporator rooms utilize these unions for pump associations. The plan permits vibration segregation whereas empowering simple pump evacuation for maintenance.

Oil and Petroleum Lines: Refineries and chemical plants depend on these fittings for prepare channeling where separable associations are essential.

Installation Instructions

  1. Prepare Pipe Strings: Clean and review NPT strings on both pipes
  2. Apply Sealant: Utilize PTFE tape or pipe dope as it were on NPT pipe strings (never on union nut threads)
  3. Hand Get together: String the male and female closes into your framework hand-tight
  4. Tighten Association: Utilize pipe torques to accomplish legitimate torque without over-tightening
  5. Final Get together: Bring union faces together and fix the union nut until snug

A: The 341 model features a brass-to-iron seat, while 340 uses iron-to-iron contact. You get better sealing performance with the brass seat design.

Q: Can I use these for potable water applications?

A: No, these fittings are designed for gas, steam, and oil applications. The black finish may affect water quality.

Q: Do I need thread sealant on union nut threads?

A: Never apply sealant to union nut threads. Only use sealant on the NPT pipe connection threads.

Q: What's the maximum temperature rating?

A: These fittings handle temperatures up to 400°F (204°C), making them suitable for most steam applications.
