SuprSafe®
Stainless Steel
Gas Connectors

Durable, naturally corrosion-resistant 304 stainless steel gas
connectors for indoor or outdoor stationary appliance applications.

Features and Specifications

• Tubing: Annealed, 304 stainless steel (ASTM A240)

• Flare nuts: Brass or plated steel

• Adapters: Brass or plated steel

• Optional coating: Heavy-duty, antimicrobial, hot-dipped gray PVC

1

(for

⁄2" OD (21 series) and 5⁄8" OD (31 series only). Coating will not

hold a flame.

• Approved for indoor/outdoor use with stationary gas
appliances/equipment

• Temperature rating of connector with adapters: -40°F to 150°F

• Temperature rating with valves: -40°F to 125°F

• 100% factory leak tested

• When installing a new appliance or when an existing
appliance is moved to a new location a NEW gas
connector must be used per manufacturer’s installation
instructions and per product standards ANSI Z21.24/CSA

6.10 and ANSI Z21.75/CSA 6.27

• Designed for occasional movement after installation. Repeated
bending, flexing or extreme vibration must be avoided. Normal
operation of a clothes dryer, rooftop HVAC unit or SIMILAR
OUTDOOR APPLIANCE DOES NOT constitute extreme
vibration or movement

NOTICE

The minimum flow capacity values in the charts are at 0.5" w.c. pressure drop (inlet pressure
minus outlet pressure). If your gas system has more available pressure drop then a general
rule of thumb approximate calculation is as follows:
Minimum Flow Capacity @ your pressure drop = Square Root (your pressure drop/0.5) x value
from chart
Example: What is the approximate minimum flow capacity (natural gas) of the Dormont 30
Series x 24" @ 1" wc pressure drop?
Answer: Square Root (1/0.5) x 150,000 = 212,132 BTU/hr
