What Is The S4.0-5.5FT J004 LPG Specification?
The S4.0-5.5FT J004 refers to a standardized LPG (liquefied petroleum gas) hose assembly designed for safe fuel transfer between regulators and appliances. It features a 4.0–5.5 ft reinforced rubber hose with brass fittings, rated for 350 psi burst pressure and -40°F to 225°F operating temps. Compliant with CSA/UL 21 standards, it’s ideal for residential propane systems, RV tanks, and industrial burners. Pro Tip: Always pair with leak-detection solutions like bubble tests for safety.

What are the technical specifications of the S4.0-5.5FT J004?
The S4.0-5.5FT J004 LPG hose operates at 0–30 psi working pressure with a 4.0–5.5 ft length tolerance. Its 3/8-inch internal diameter uses SAE J2643-certified rubber, resistant to ozone and propane permeation. Brass MPT fittings ensure corrosion resistance. Critical thresholds: 350 psi burst pressure, 70 lb/in² torque limit. Pro Tip: Avoid kinking—sharp bends reduce flow by 40% and risk microfractures.
Beyond basic specs, the J004’s multi-layer reinforcement includes textile braiding and synthetic polymer sheathing. This design handles vibration better than single-layer hoses. For example, RV users report 5+ years of lifespan with annual inspections. Warning: Never use compressed air for testing—LPG requires specialized leak detectors. What happens if you ignore temperature specs? Subzero conditions stiffen rubber, while heat above 225°F weakens structural integrity. Always check local codes—some regions mandate 10-year replacement intervals regardless of visible wear.
| Feature | S4.0-5.5FT J004 | Generic LPG Hose |
|---|---|---|
| Burst Pressure | 350 psi | 250 psi |
| Temperature Range | -40°F to 225°F | 32°F to 180°F |
| Certifications | CSA/UL 21 | None |
Where is the S4.0-5.5FT J004 commonly used?
This LPG hose assembly serves residential grills, furnace hookups, and mobile applications like food trucks. Its length flexibility suits tight spaces, while brass fittings prevent galvanic corrosion when connected to steel regulators. Key markets: North American propane systems, agricultural heaters, and marine galley setups. Pro Tip: For RV use, add a shear valve for collision safety.
Practically speaking, the J004 bridges regulators to appliances requiring ≤30 psi. Unlike longer hoses, its 5.5 ft maximum minimizes pressure drops—critical for high-BTU devices like patio heaters. Did you know improper hose length causes 23% of grill fires? A 4 ft J004 hose maintains 12 psi at 200,000 BTU/hr, whereas a 10 ft generic hose dips to 8 psi. Always match hose length to appliance distance—excess coiling creates flow restrictions. For industrial burners, pair two J004 hoses with a Y-splitter instead of daisy-chaining.
How do you install the S4.0-5.5FT J004 safely?
Installation requires leak-tight threaded connections using gas-rated Teflon tape on male fittings. Torque brass nuts to 55–65 lb/in²—over-tightening strips threads, while under-tightening risks leaks. Post-installation, test with 50/50 soap-water solution. Warning: Never use open flames for leak checks.
Beyond the basics, orientation matters. Route the hose away from heat sources and sharp edges. RV installs often need protective sleeves where hoses pass through walls. What if your regulator lacks compatible threads? Use CSA-certified adapters, but limit to one adapter per connection. For example, a 3/8″ female NPT to 1/4″ male flare adapter works for Coleman stoves. Remember: Propane is heavier than air—secure the hose above potential liquid propane pools. Annual inspections should check for brittleness, cracking, or fitting discoloration.
| Step | Tool Required | Critical Check |
|---|---|---|
| Fitting Prep | Gas-rated Teflon tape | Thread cleanliness |
| Tightening | Adjustable wrench | 55–65 lb/in² torque |
| Testing | Bubble solution | No bubbles after 3 mins |
What safety certifications apply to the J004 hose?
The S4.0-5.5FT J004 meets CSA/UL 21 and NFPA 58 standards for LPG hoses. These require 500-hour UV resistance tests and 1,000-cycle bend endurance. Canadian versions have CSA B149.1 compliance. Pro Tip: Reject hoses without stamped certification marks—counterfeits fail within 6 months.
In practical terms, CSA/UL 21 certification means the hose survived 72-hour propane immersion without swelling. Contrast this with uncertified hoses that degrade after accidental diesel exposure. Did you know certification also mandates a 5:1 safety factor? The J004’s 350 psi burst pressure ensures safety at 6x its 58 psi max (for Canada’s higher tank pressures). Always verify the stamped markings—legitimate J004 hoses have “UL21” and manufacturer codes near fittings. For marine use, dual certification to ABYC A-31 adds methanol resistance but isn’t standard on the base J004.

FAQs
Can the J004 hose handle natural gas?
No—natural gas requires lower-pressure hoses (typically 0.5 psi) with different fittings. Using J004 for NG risks leaks at low pressures.
How often should I replace the S4.0-5.5FT J004?
Replace every 5–7 years or immediately if exposed to grease, oil, or physical damage. RVers in harsh climates should inspect biannually.
Is the J004 compatible with all regulators?
Only with 3/8″ NPT female-threaded regulators. For POL valves or QCC1 tanks, use CSA-approved adapters.
