RV LP Line Materials - Copper, CSST, and When Each Is Used and Why
Hard drawn copper tubing (ASTM B88 Type L, 3/8-inch outside diameter) has been the standard RV LP supply material since the 1970s. It is durable, easily bent to routing requirements, and resists corrosion well in Florida's humidity. Its weakness is point-load fatigue from vibration when it contacts metal frame members - the copper wall is 0.030 inches thick on 3/8-inch Type L, which is not enough to resist abrasion from repeated micro-contact with steel edges under road vibration. Corrugated stainless steel tubing (CSST, AGA ANSI LC 1 rated) is increasingly used for RV LP distribution because its corrugated wall distributes vibration stress without work-hardening - the same failure mechanism that causes copper pinhole leaks. CSST requires bonding to the RV chassis at installation to prevent lightning-induced arc-through, which can perforate the steel wall. NFPA 58 Section 6.12 requires all LP line repairs to use materials rated for LP service at 250 PSIG working pressure - standard household plumbing copper (ASTM B88 Type M) is not rated for LP service and must not be used for RV LP repairs. Jesse Earl carries 10-foot coils of Type L and CSST in 3/8-inch and 1/2-inch sizes on every LP line repair call.
LP Line Fitting Types for Field Repairs - Flare vs. Compression vs. Push-Connect
Three fitting types are used for RV LP line field repairs. Inverted flare fittings (Parker 60C series, SAE 45-degree flare) are the OEM standard on most RVs and provide the highest-integrity mechanical seal - the flared copper seat provides a metal-to-metal seal that does not depend on an elastomeric O-ring. Compression fittings (Parker CPI series) use a brass ferrule crushed onto the copper tube OD - acceptable for LP service but not recommended for buried or concealed runs where they cannot be re-checked for tightening after the first thermal cycle. Push-connect fittings (SharkBite brand) are not rated for LP gas service and must not be used for any RV LP repair regardless of pressure rating shown on the packaging - the SharkBite elastomeric seal is not LP-compatible and the connection is not listed under ANSI LC 4. Jesse Earl uses Parker 60C inverted flare fittings exclusively for all field LP line repairs because they do not require re-tightening after the first thermal cycle and can be leak-tested immediately after installation.

Case Study: LP Line Repair Repair
RV: 2022 Coachmen Freelander 22XG • Location: Cayo Costa State Park, Site 8 • City:
Symptom: LP gas odor strongest under the galley, detectable at the exterior LP compartment door; furnace and range both operated normally; LP tank level dropping faster than expected given current usage pattern
Diagnosis: Jesse Earl pressurized the LP system to 11.0 WC and scanned with the Bacharach Leakator Jr. Detected 320 ppm reading along the 3/8-inch copper tubing run under the galley floor, approximately 18 inches past the galley floor penetration grommet. Removed the galley base cabinet access panel and found a 0.5-inch section of copper tubing with a pinhole visible under a 4x magnifier, located at a point where the line contacted a sharp edge of the galley frame steel. The frame contact had abraded through the copper wall over 3 years of road vibration.
Outcome: Post-repair leak test: 0 ppm at all points on repaired section and all downstream connections; system held 11.0 WC pressure over 10-minute lockup test with no pressure drop; no LP odor detected interior or exterior after repair

LP Line Materials - Specifications for RV Repair Applications
| Material | Standard | Working Pressure | Vibration Resistance | Field Joining Method | Florida Corrosion Resistance |
|---|---|---|---|---|---|
| Copper Type L (3/8-inch OD) | ASTM B88 | 250 PSIG at 150 F | Moderate - point-load susceptible | Inverted flare or compression | Excellent |
| Copper Type M (3/8-inch OD) | ASTM B88 | 150 PSIG - NOT LP rated | Moderate | Not allowed for LP | Excellent |
| CSST (3/8-inch ID) | ANSI LC 1 | 250 PSIG at 250 F | Excellent - corrugation distributes stress | CSST proprietary fitting | Excellent (SS) |
| Aluminum tubing (3/8-inch) | ASTM B210 | 250 PSIG | Poor - work-hardens faster than copper | Compression only | Moderate (oxidation) |
| Rubber LP hose (3/8-inch) | ANSI Z21.45 | 350 PSIG | Excellent - flexible | Barb + clamp (not flare) | Good (UV degrades jacket) |
Signs You Need LP Line Repair
- ✓Identify leak location with electronic detector before cutting any tubing
- ✓Depressurize and vent system before making any cuts
- ✓Cut out minimum 6 inches past the visible damage on both sides of the defect
- ✓Deburr cut tubing ends with tube deburring tool before flaring
- ✓Form 45-degree SAE flares with calibrated flaring tool (depth gauge required for consistent flare)
- ✓Inspect flare for cracks, oval cross-section, or incomplete formation before installing fitting
- ✓Apply thread sealant to NPT threads only - never to flare seats
- ✓Route repaired section clear of all metal contact points with 0.5-inch minimum clearance
- ✓Install chafe protection at any point within 2 inches of metal frame members
- ✓Leak-test repaired section at operating pressure before restoring access panels
- ✓Perform 10-minute pressure lockup test: system must hold 11.0 WC without drop
