Short answer

The .710 in OD size is the largest 1/2 in tubing: Raindrip's 062010P and DIG's TS100/TS500 are .620 x .710 in (ID x OD), and Rain Bird's T71 is 0.71 in OD. DIG's blue-insert C43, C45 and C46 compression fittings list it, as do Smart Loc, Orbit 67466 and Orbit 67491. Rain Bird's Easy-Fit range stops at 0.70 in. See joining .700 to .620 or .710.

Key facts

Names it is sold under
1/2 in or .710 tubing. Rain Bird sells T71 (0.71 in OD) and its store calls a T71 coil '.710 Blank Tubing'; Raindrip calls 062010P 0.710 in supply tubing[1][2][3][4]Rain Bird's store does not say whether .710 is the OD or the ID; Rain Bird's product page gives 0.71 in OD.
Outside diameter
.710 in (Raindrip 062010P, DIG TS100/TS500); 0.71 in (Rain Bird T71)[3][5][1]
Inside diameter
.620 in (Raindrip 062010P, DIG TS100/TS500, Raindrip's Smart Loc pair). Rain Bird gives no ID for T71[3][5][6][1]
Tubing makers list at this size
Raindrip 062010P (100 ft coil); DIG TS100 and TS500; Rain Bird T71-100S and T71-500S[3][5][1]
Maker pressure rating
Rain Bird: 70 psi for T71. Raindrip states none on its 062010P page[1][3]
Compression fittings for this OD
DIG blue insert (.710 in OD): C43 coupling, C45 tee and C46 elbow. Rain Bird Easy-Fit is listed for 0.63-0.70 in OD, which does not include 0.71 in[7][8]
Locking-nut and universal fittings
Raindrip Smart Loc S5600UB (.620 x .710 in, up to 50 psi); Orbit 67466 (.620-.710 in OD); Orbit 67491 Drip-Lock push-on (.690, .700 and .710 in OD); DIG NUTLOC (.620 in ID, within .630-.710 in OD)[6][9][10][11]
Barbed fittings
Not confirmedNo source in our register ties a 1/2 in barbed insert fitting to .620 x .710 in tubing.
Reducers and adapters
DIG D50B reducing coupling (blue): joins .700 in OD to .710 in OD tubing[7]
End closures, plugs and stakes
Raindrip 646050B goof plugs (50-pack), listed for 1/2 in, 5/8 in and 0.710 in supply tubing. Orbit 67468 end cap (.620-.710 in OD)[4][12]
How to identify it
Read the print on the tubing first. Then cut a fresh, square end and measure the OD across the outside with calipers; a reading near .710 in puts it in this size. Drip Depot says to check a tube's ID and OD before buying fittings. Steps: [how to measure drip tubing](/guides/how-to-measure-drip-tubing); lookup: [tubing size finder](/tools/drip-tubing-size-finder)[13]
Maker-page conflicts
DIG's .710 spec line prints a wall figure that does not match its own .620 x .710 in ID and OD, so we quote ID and OD only. Rain Bird's store labels a T71 coil '.710' without saying OD or ID[5][2]
Not confirmed
Not confirmedRain Bird states no ID for T71. Raindrip states no pressure rating for 062010P. No source gives a measuring tolerance.

Watch out for

  • Rain Bird lists Easy-Fit for 0.63-0.70 in OD, so it does not list it for T71 (0.71 in).
  • DIG uses a blue insert for .710 in OD; the black insert is for .700 in.
  • DIG's .710 page prints a wall figure that does not add up. Ignore it and match ID and OD.
  • Raindrip's 646050B goof plugs name 0.710 in supply tubing but say nothing about 1/4 in tubing.
