For distributors, project buyers, and private-label brands, supplying plastic valves and pipe fittings to different markets requires more than choosing a product type. The pipe outside-diameter system, socket standard, thread option, and product configuration must match the confirmed installation requirement.
JARO’s standard plastic valve and pipe fitting range covers 20–110 mm sizes across its product lines, supporting common requirements for joining, reducing, branching, threaded transitions, and flow control. For sizes outside this standard range, JARO can discuss separate mold development and production according to confirmed project requirements.
Across its plastic valve and pipe-fitting product lines, JARO supports product development and production with more than 2,000 molds. This company-wide tooling base supports a broad product system for irrigation, water distribution, and compatible piping applications.
Pipe-Size Systems and Thread Systems Are Separate Selection Points
Socket-end dimensions identify the compatible pipe outside diameter. BSPT and NPT identify threaded outlet options. They solve different connection requirements and should be confirmed separately when a product combines a socket or compression pipe connection with a threaded end.
| Connection area | Options used across relevant product series | What must be confirmed |
|---|---|---|
| Socket or compression pipe connection | DIN, GB, ANSI, JIS, B.S., or CNS, where specified | Pipe outside diameter, selected product size, and applicable dimensional table |
| Threaded outlet | BSPT or NPT, where specified | Nominal thread size, male/female mating part, sealing method, and product drawing |
These options describe available configurations, not a blanket compliance claim for every model. Final selection should always refer to the relevant product specification.
PP Compression Fittings for Pipe Connections and Threaded Transitions
JARO’s core standard PP compression fitting range covers 25–110 mm pipe sizes, while some individual configurations may also be available in 20 mm. The range supports system functions such as joining, reducing, branching, transitioning to threaded equipment connections, and flow control. Product-specific size combinations and pressure ratings must be checked on the selected product page.
A PP reducing tee compression fitting provides a three-way connection with a reduced branch. A PP double compression ball valve provides flow control in compatible plastic-pipe systems. A PP male threaded adapter provides a compression-to-male-thread transition where the selected thread standard and mating component are confirmed.
PP Pipe-Size Dimensional Reference
The following dimensional reference applies to the pipe-side options shown for the PP fitting range. All values are in millimetres. Check the exact model and drawing before ordering because not every product is offered in every listed configuration.
| Reference pipe size (mm) | DIN | GB | ANSI | B.S. |
|---|---|---|---|---|
| 20 | 20 | 20 | 21.34 | 21.2 |
| 25 | 25 | 25 | 26.67 | 26.6 |
| 32 | 32 | 32 | 33.40 | 33.4 |
| 40 | 40 | 40 | 42.16 | 42.1 |
| 50 | 50 | 50 | 48.26 | 48.1 |
| 63 | 63 | 63 | 60.33 | 60.2 |
| 75 | 75 | 75 | 73.00 | 73.0 |
| 90 | 90 | 90 | 88.90 | 88.7 |
| 110 | 110 | 110 | 114.30 | 114.1 |
PVC-U Ball Valves for Socket and Threaded Configurations
PVC-U ball valves extend this multi-standard configuration capability to fluid-control applications. The PVC-U double union ball valve is available with socket or threaded connection options; its product specification lists ANSI, DIN, JIS, and GB socket standards, with BSPT and NPT thread standards. Its available size range, working pressure, temperature range, and final connection selection depend on the selected configuration.
The PVC-U octagonal ball valve is available with socket or threaded end connections. Its product page lists DIN, GB, ANSI, JIS, B.S., and CNS compatible socket configurations. Confirm the required end connection and product drawing before selection.
BSPT and NPT Thread Options
BSPT and NPT are different thread systems. They should not be treated as interchangeable without confirming the mating component and installation requirement.
| Thread option | Official reference | Confirm before ordering |
|---|---|---|
| BSPT | ISO 7-1 | Nominal thread size, mating part, sealing method, and selected product drawing |
| NPT | ASME B1.20.1 | Nominal thread size, mating part, sealing method, and selected product drawing |
Confirm the Exact Product Configuration Before Ordering
Before selecting a PP fitting or PVC-U ball valve for a project, confirm:
- Product series, model, material, and required connection type
- Pipe outside diameter and applicable DIN, GB, ANSI, JIS, B.S., or CNS option where available
- BSPT or NPT thread requirement where a threaded connection is used
- Exact product size, pressure rating, temperature range, seal material, and applicable medium
- Project-specific installation, packaging, and OEM/ODM requirements
For configurations outside a standard product range, JARO can discuss separate mold development and production after reviewing confirmed project requirements.
Discuss Your Standard and Connection Requirements
Share the required product type, pipe-size system, connection standard, thread option, operating conditions, and target application with JARO. We can help review the relevant product configuration and related valves or fittings for your project.

Frequently Asked Questions
Do all JARO plastic valves and fittings support every listed standard?
No. Standard options depend on the product series, model, size, and connection type. Refer to the selected product page and drawing to confirm the available configuration.
What is the difference between a pipe-size system and a thread system?
A pipe-size system identifies the compatible socket or compression pipe outside diameter. A thread system identifies the threaded connection. Both must be selected to match the relevant pipe and mating component.
Are BSPT and NPT interchangeable?
No. BSPT and NPT are different thread systems. Confirm the required thread option, mating component, and sealing method for the selected installation.
Can JARO discuss custom product development for non-standard requirements?
Yes. JARO can discuss separate mold development and production after reviewing the confirmed dimensions, material, connection type, operating conditions, order quantity, and development requirements.
