AI-generated imageMueller Streamline Type L copper tube is a seamless, phosphorus-deoxidized copper tube manufactured to ASTM B88, with a wall thickness that sits intermediate between the thicker Type K (used for underground water mains and high-pressure applications) and the thinner Type M (used only where local code permits lower-pressure residential service). This middle-ground wall thickness makes Type L the standard choice for interior above-ground plumbing, giving it enough pressure rating and corrosion margin for both hot and cold water lines in virtually every plumbing code, without the added cost and weight of Type K.
Plumbing contractors, HVAC installers, and mechanical engineers rely on Mueller Streamline Type L wherever code-compliant interior water, fire protection, solar, fuel/oil, or HVAC piping is being run — domestic water distribution, compressed air lines, and LPG gas systems are common applications, though copper is explicitly not permitted by US code for natural gas distribution. Each length is incised-marked and blue color-coded along its length specifically so contractors can identify Type L tube on a job site at a glance, without needing to measure wall thickness to confirm type. The tube is seamless with a smooth interior for unrestricted flow and good heat transfer, and it's manufactured, marked, and color-coded to meet NSF/ANSI 61 standards for safe drinking water contact.
Common configuration: 1" nominal size with a 1-1/8" actual outside diameter (copper tube OD always runs 1/8" larger than its nominal size designation), 0.050" wall thickness at the 1" nominal size, hard (drawn) temper for rigid straight-length installation, blue color-code marking for Type L identification, manufactured to ASTM B88 and NSF/ANSI 61, alloy C12200 phosphorus-deoxidized copper, and sold in straight lengths commonly available at 1 ft, 5 ft, 10 ft, and 20 ft — Mueller's LH1000 designation covers the 1" Type L hard tube line across these length options (e.g., LH10005 at 5 ft, LH10010 at 10 ft), priced and specified per foot for ordering purposes. Made in the USA.
Stop second-guessing. Match your use case below — then let ChatMRO's AI surface the exact length and alternatives in one natural-language search.
Small repairs, short branch connections, or fitting-to-fitting runs. Shorter 1 ft and 5 ft lengths dominate here.
Typical interior plumbing and HVAC runs across a room or floor. The 10 ft length dominates here.
New construction or larger commercial projects needing longer continuous runs and fewer total joints.
Mueller Streamline's Type L copper tube line spans multiple standard lengths at the 1" nominal size, all manufactured to the same ASTM B88 specification. Here's how to navigate the range without a 40-tab browser session.

Search LH1000 Series (20 ft and Per-Foot) →Use this table as a decision shortcut. Ask ChatMRO for the exact part once you know which row fits your spec.
| Type/Length | Wall Thickness | Length | Best For | Temper | Color Code | ChatMRO Verdict |
|---|---|---|---|---|---|---|
| Type L, 1 ft | 0.050" | 1 ft | Small repairs, spare stock | Hard | Blue | Best for minimizing waste on short repair jobs |
| Type L, 5 ft (LH10005) | 0.050" | 5 ft | Short branch runs, repair jobs | Hard | Blue | Good for moderate-length repair or branch connections |
| Type L, 10 ft (LH10010) | 0.050" | 10 ft | Standard residential/commercial plumbing runs | Hard | Blue | Most common choice for typical interior plumbing runs |
| Type L, 20 ft | 0.050" | 20 ft | Larger installations, fewer joints per run | Hard | Blue | Use for longer continuous runs to reduce joint count |
| Type K (comparison) | 0.049" (at 1/2" size; thicker overall) | Various | Underground mains, high-pressure applications | Hard or soft | Green | Use when underground burial or higher pressure rating is required |
| Type M (comparison) | 0.028" (at 1/2" size; thinner overall) | Various | Low-pressure residential water supply where code permits | Hard | Red | Not suitable for all jurisdictions — confirm local code before selecting |

Whether you're a plumbing contractor specifying tube for a new water service, or an HVAC installer running refrigerant or hydronic lines — use this framework before you procure.
Type L is the standard for interior above-ground plumbing and is code-approved for both hot and cold water — confirm your specific application (underground burial, high-pressure) doesn't actually call for thicker Type K instead.
A 1" nominal Type L tube has a 1-1/8" actual outside diameter — confirm your fittings and connections are sized to this actual OD, not the nominal designation.
Shorter lengths (1-5 ft) suit repairs and short branches; 10 ft is the most commonly stocked standard run length; 20 ft reduces total joint count on longer continuous runs.
Confirm the specific tube you're ordering carries NSF/ANSI 61 certification if it will carry drinking water, as required by most plumbing codes.
Confirm your local code and application — copper tube is not permitted by US code for natural gas distribution due to potential cracking from odor additives, moisture, and certain solder types.
A '1 inch' copper tube has a 1-1/8" actual OD, not exactly 1 inch — confirm your fitting selection accounts for this before ordering. Search by function on ChatMRO — the AI surfaces exact matches AND available substitutes at the correct actual dimension for your fittings.
Type M's thinner wall is only permitted in some jurisdictions for low-pressure residential use, and many codes don't allow it for hot water lines at all — confirm your local code's minimum requirement before substituting a thinner-wall tube to save cost.
Copper tube is not code-approved for natural gas distribution in the US — use appropriately rated gas piping material instead, regardless of the copper tube's pressure rating for other fluids.
Describing your application to ChatMRO takes 30 seconds. The AI reads the full Mueller Streamline copper tube catalogue so you don't have to.
The three types differ in wall thickness at the same nominal size — Type K is thickest (used for underground mains and high-pressure systems, green color-coded), Type L is intermediate (the standard for interior plumbing, blue color-coded), and Type M is thinnest (used only where local code permits lower-pressure residential service, red color-coded). Search all three types on ChatMRO to compare pricing and availability instantly.
A 1-inch nominal copper tube has an actual outside diameter of 1-1/8 inches — copper tube nominal sizing is traditionally 1/8 inch smaller than the tube's actual OD, a legacy convention distinct from how steel or PVC pipe is sized. ChatMRO can surface tube at the correct actual dimension for your fitting compatibility from a single description search.
1-inch Type L copper tube, with its 0.050-inch wall thickness, weighs approximately 0.655 pounds per foot — a standard 20-foot length weighs roughly 13.1 pounds, useful for estimating shipping weight and structural support needs along a run. ChatMRO provides access to manufacturer weight specifications directly from search results.
No — copper tube is not permitted by US code for natural gas distribution due to potential cracking risk from odor additives, moisture content, and certain solder types used in gas system joints, regardless of the tube's pressure rating for other fluids.
