10-32 thread on drip emitters, jets and risers
Some emitters and jets screw on with a 10-32 thread: Rain Bird Xeri-Bug -1032 models, DIG's bare jet heads and Rain Bird's PFR-12 riser.
Also listed as 10/32, 10-32 riser thread
Short answer
10-32 is a small screw thread on some emission devices. Rain Bird sells Xeri-Bug emitters with a 10-32 inlet (the -1032 models) and a PFR-12 PolyFlex riser for 10-32 threaded devices at 15-50 psi. DIG sells its adjustable jets as bare 10/32 heads (300B, 308B, 309B) or as assemblies with a stake, riser and 1/4 in barb. See micro-sprays, jets and bubblers.
Key facts
- How it grips
- A threaded device screws onto a 10-32 riser or stake: Rain Bird's PFR-12 riser takes 10-32 threaded emission devices[1]
- Dimension that decides fit
- The thread on the device and the riser: 10-32 (Rain Bird), written 10/32 by DIG[2][3]
- Ranges makers state
- Rain Bird Xeri-Bug -1032 models (10-32 inlet, barb outlet). DIG 300B, 308B and 309B: bare 10/32 jet heads (2-pack). DIG 300-1B, 308-1B and 309-1B: assemblies with a 13 in stake, 12 in riser and 1/4 in barb[2][3]
- Maker pressure ratings
- Rain Bird PFR-12 riser: 15-50 psi. Rain Bird Xeri-Bug: 15-50 psi. DIG adjustable jets: 15-30 PSI[1][2][3]
- Reuse and removal
- Not confirmedNo source in our register covers unscrewing and reusing 10-32 devices.
- Meets directly
- Rain Bird's PFR-12 PolyFlex riser works with 10-32 threaded emission devices and can be used with the RS-025T riser stake[1]
- Needs an adapter to meet
- 1/4 in tubing: DIG's -1B jet assemblies end in a 1/4 in barb; Rain Bird's Xeri-Bug also comes with a barb inlet (XB-05PC, XB-10PC, XB-20PC) instead of 10-32[3][2]
- Common mistakes makers name
- Ordering a bare head when you need the whole assembly: DIG's 'B' models are 10/32 heads only, while its '-1B' models include the stake, riser and 1/4 in barb[3]
- Not confirmed
- Not confirmedNo source gives 10-32 thread dimensions or confirms that Rain Bird and DIG 10-32 parts interchange.
Watch out for
- DIG's 300B, 308B and 309B are bare 10/32 heads; the stake, riser and 1/4 in barb come only with the -1B assemblies.
- Xeri-Bug comes in three inlet types: barb, 10-32 thread (-1032) and 1/2 in FPT (XBT-10, XBT-20). Pick the inlet before the flow.
- DIG rates its jets 15-30 PSI, a narrower range than Rain Bird's 15-50 psi riser.
- CSU Extension advises putting micro-sprays on a separate zone because they use much more water than drippers.
Questions
What is a 10-32 thread on a drip emitter?
A small screw thread some devices use instead of a barb. Rain Bird sells Xeri-Bug emitters with a 10-32 inlet and the PFR-12 riser for 10-32 threaded devices.[2][1]
Do DIG jet heads come with a riser?
Only the -1B assemblies (300-1B, 308-1B, 309-1B), which include a 13 in stake, 12 in riser and 1/4 in barb. The 300B, 308B and 309B are bare 10/32 heads.[3]
