Advanced Specialty Gas Equipment

TRB Series
Modular, Double Row, High Purity Manifolds

Double Row Manifolds are used to connect four or more cylinders together for greater on-line storage capacity or higher flow rates. These double-row brass manifolds are designed for pedestal mounting and are provided with diaphragm seal station valves, 3-ft pigtails(stainless steel CGA connections with flexible pigtail option) and mounting brackets. They are ideal for installations where wall space is at a premium.

The TRB Series manifolds are manufactured to meet the requirements of the ASME B31.3 Process Piping Code. They are constructed of 7/8 inch OD 0.200 wall CDA-330 brass seamless tubing, npt threaded and silver braze assembled. ASGE's enhanced manifold header design exceeds industry standards by providing a 4 to 1 - burst to maximum operating pressure safety factor.

Warning: Manifolds are designed to distribute a single gas from two or more cylinders. Never mix gases in a manifold. Injury to personnel or damage to equipment may result.

Standard Features
  • Modular Construction allows field installation of additional stations without welding or soldering.
  • Diffusion Resistant, Diaphragm Seal Station Valves ensure that gas purity is maintained and allow cylinder removal from a manifold without interrupting gas flow.
Optional Features
  • Master Shut-off Valve allows manifold to be isolated from downstream system.
  • Double-Braided (All Metal) 3' Stainless Steel Flexible Hose Pigtails with Stainless Steel CGA connections extend service life and provide ease of connecting cylinders.
  • Check Valves prevent discharge of gas from manifold and pigtails when changing cylinders (required for flammable gases).
  • Pressure Switches monitor line pressure and can activate an external alarm when a certain predetermined pressure is reached.

Ordering Information

To order a double row manifold, complete the part number using the "Part Number Key". For example, to order an 8 cylinder, double row manifold with rigid pigtails, check valves, and with CGA 540 connections, the part number would beTRB-4-8-540. Order by complete part number.

Manifolds for Acetylene Service require flash back arrestors (SG6545). All manifolds ordered with CGA 510 will be shipped with flashback arrestors installed on each pigtail, unless the order specifies with which gas it will be used.

Double Row (nonmodular) manifolds are available in stainless steel construction. Contact your Advanced distributor for additional information.
