1/2 inch drip tubing whose maker states the OD: Rain Bird T63 at 0.63 in; T70, Drip Depot and DripWorks at .700 in; Raindrip 062010P at .620 x .710 in.

Short answer
Five approved 1/2 in tubing coils have an outside diameter stated by their maker. Choose Rain Bird T63 for tubing at about 0.63 in OD; Rain Bird T70, Drip Depot's or DripWorks' .600 x .700 in tubing for 0.700 in; or Raindrip 062010P for .620 x .710 in. Buy the one that matches the tubing already in the ground.
How we chose
A coil is on this list only if:
- The maker states the OD. "1/2 in" is sold at several sizes: DIG lists .600 x .700 in (ID x OD),[1] Raindrip's 062010P is .620 x .710 in,[2] and Rain Bird sells T63, T70 and T71 at 0.63, 0.70 and 0.71 in OD.[3] Mister Landscaper's MLT-71 and MLT-72 are .600 x .700 in.[4]
- The ID is stated, or its absence is flagged. Rain Bird gives no ID for T63, T70 or T71,[3] so we say so on each Rain Bird pick.
- It is in our approved catalog with a store listing.
Five coils met this bar on 2026-10-15. We do not add others to fill the list.
For tubing at about .620-.630 in OD
Rain Bird T63‑100 1/2 in blank distribution tubing (0.63 in OD, 100 ft)
Pick it if: Extending or repairing a line of 0.63 in OD tubing, with compression or locking-nut fittings listed for that OD
- Why it's here
- Rain Bird lists T63 1/2 in blank distribution tubing at 0.63 in OD with a 70 psi pressure rating.
- Watch out
- Rain Bird does not state the inside diameter, so barbed fittings that depend on the ID cannot be matched from Rain Bird's numbers. On Amazon, check that 'Ships from / Sold by' shows Amazon.com or Rain Bird.
- Tubing inside and outside diameter
- 0.63 in OD; Rain Bird does not state the inside diameter
- Nominal size family (1/2 in, 3/4 in, 1/4 in, metric 4/7 mm, 16 mm)
- 1/2 in (0.63 in OD, standard wall)
- Fitting connection type (compression, barbed insert, spin-lock, hose thread, pipe thread)
- Takes Rain Bird 1/2 in barbed or compression fittings; 1/4 in barbed couplings and drippers tap into the side

- Not stated
Values are the manufacturer's specs unless marked.
For tubing at .700 in OD

Pick it if: Systems built on .700 in OD tubing, with fittings listed for .700 in OD
- Why it's here
- Rain Bird lists T70 tubing at 0.70 in OD, the same OD DIG and Mister Landscaper list for their 1/2 in tubing; Rain Bird gives one 70 psi rating for the T63, T70 and T71 family.
- Watch out
- A matching OD is a size match only; no maker states cross-brand fit, and Rain Bird gives no ID. On Amazon, check that 'Ships from / Sold by' shows Amazon.com or Rain Bird.
- Tubing inside and outside diameter
- 0.70 in OD; Rain Bird does not state the inside diameter

Fit at a glance
| Tubing | OD | ID | Pressure rating | Coil |
|---|---|---|---|---|
| Rain Bird T63-100 | 0.63 in | Not stated | 70 psi | 100 ft |
| Rain Bird T70-100S | 0.70 in | Not stated | 70 psi (family rating) | 100 ft |
| Drip Depot 1/2 in poly tubing | 0.700 in | 0.600 in | Not stated | 100 ft |
| DripWorks 1/2 in mainline tubing | 0.700 in | 0.600 in | 50 psi, not for constant pressure | 50 ft |
| Raindrip 062010P | 0.710 in | 0.620 in | Not stated | 100 ft |
Drip Depot's page gives the size and length only.[5] DripWorks lists 50 psi and says to install its tubing downstream of timers, valves and regulators, since it is not rated for constant pressure.[6] Rain Bird's store lists T63 at 0.63 in OD with a 70 psi rating.[7] Rain Bird's product page gives one 70 psi rating for the T63, T70 and T71 family.[3] Raindrip's page states no pressure rating for 062010P.[2]
Matching OD is not the same as cross-brand fit
Rain Bird's T70, DIG's, Drip Depot's and DripWorks' .700 tubing share an OD. DripWorks names .700 OD compression and standard 1/2 in insert fittings for its tubing, but no maker on this page names another brand's fittings by model. Pair the tubing with fittings whose maker lists that OD; the mainline fittings hub and the tubing size finder show which ones do.
See the 1/2 in size guide and the mainline tubing hub.
Questions
Which of these fits my tubing?
The one at your tubing's OD: T63 for about 0.63 in; T70, Drip Depot or DripWorks for 0.700 in; Raindrip 062010P for 0.710 in. See how to measure drip tubing.[3][2][5][6]
Is Rain Bird T70 the same as DIG .700 tubing?
They match by OD: Rain Bird lists T70 at 0.70 in OD and DIG lists .600 x .700 in. Rain Bird gives no ID, and neither maker states that the two are interchangeable.[3][1]
Why is there no 3/4 in tubing here?
This list covers 1/2 in sizes. For 3/4 in, compare a listing's ID and OD with DIG's .820 x .940 in; see the mainline tubing hub.
