Short answer
Orbit has two 1/2 in lines. The Universal 67466 coupling and 67468 end cap use a hand-twisted nut, are reusable and are listed for .620-.710 in OD. The Drip-Lock 67491 coupling pushes on, has a release tab and is listed for .690, .700 and .710 in OD. Orbit's Drip-Lock collection page lists no ODs, so check each product page. See universal fittings explained.
Key facts

- Maker cautions
- Orbit gives the fit as an OD range, '.620-.710 in OD', next to its 'most major brands' wording; the range is the fit[1][2]
- Parts the maker lists for it
- Orbit's collection lists Drip-Lock items such as the 67491 coupling and 67492 tee, some labeled Universal Push-Fit. The 67491 page names Orbit 1/2 in, 5/8 in Raindrip, Toro Blue Stripe, 1/2 in DIG and 1/2 in Mister Landscaper tubing as compatible (Orbit's claim)[4][3]No separate locking-collar line was shown on Orbit's collection page.
- Maker-page conflicts
- Orbit's Drip-Lock collection page lists fittings by nominal size only and states no ODs; the ODs come from each product page[4][3]
- Not confirmed
- Not confirmedNo pressure rating or thread data for these fittings was confirmed. Orbit's brand compatibility list is its own claim, not a measured fit.
Watch out for
- Orbit's Drip-Lock collection page lists no ODs. Check the product page: 67491 lists .690, .700 and .710 in.
- The 67491 Drip-Lock range starts at .690 in OD, so it does not list .620 tubing; the nut-lock 67466 does.
- 'Most major brands' is Orbit's wording. The stated range, .620-.710 in OD, is the fit.
- Some Drip-Lock items are labeled Universal Push-Fit, a different line from the nut-lock 67466.
