Brass Gauge Adapters

Preventing leak paths in compact pressure systems often comes down to the smallest fittings. Our Brass Gauge Adapters solve misalignment or thread mismatch using tight-tolerance connections in multiple formats.

Connection Type

Gauge Port (1/4″ NPT, G1/4 BSP, etc.), Process Port (NPT, BSP, Metric)

Pipe Size

1/8″ – 1″ (NPT/BSP) / M5 – M25 (Metric)

Material

C36000 (Free-Cutting Brass), CW617N (EN), C37700 (High-Strength)

Dimensions

Length – 0.5″–2″ / Body Diameter – 0.3″–1″

Thread Type

NPT, BSPT, BSPP, Metric, G (ISO 228)

Product Description

Connection types include NPT, BSP, and metric options with straight, 45°, or 90° angles to suit various layout needs. Sizes range from 1/8″ to 1″ with pressure ratings up to 3,000 PSI for high-load environments.

Hexagonal Body

0.375″–0.875″ (e.g., 1/4″ NPT: 7/16″ hex)

Angle

Straight (0°), 90° Elbow, 45° Elbow

Pressure Rating

150 PSI – 3000 PSI (10.3 – 207 bar) (Size-dependent)

Temperature Range

-20°F to 400°F (-29°C to 204°C) (Non-flammable fluids)

Thread Precision

Class B (ASME B1.20.1), Grade B (ISO 228)

Material Compatibility

Air, Water, Oil, Steam, Refrigerants (No chlorides/ammonia)

Finish

Natural Brass, Electroless Nickel (ENP), Chrome, PTFE-Coated

Weight

0.02 lb – 0.5 lb (Size-dependent)

Application

Pressure Gauges, Transmitters, Manometers, Hydraulic/Pneumatic Systems

IP Rating

IP65 (Splash-proof with sealed threads)

Certifications

ASME B40.100, EN 837, ISO 19879, RoHS, NSF/ANSI 61 (Potable Water)

Technical Advantages

Thread sealing in high-vibration or multi-fluid setups can often fail with poor mating quality. Our adapters use fine-grade threads per ASME B1.20.1 and ISO 228, reducing leak risk and installation time. 
 
Electroless nickel and PTFE finishes enhance surface hardness while resisting oil, steam, or water-based corrosion. We offer straight and angled bodies with hex widths from 3/8″ to 7/8″, simplifying tool access in tight zones.

Industry Applications

Hydraulic Test Benches

Links pressure gauges or sensors to test ports without system teardown. 

Refrigeration Units

Provides sealed gauge access for refrigerant lines, preventing pressure drops.

Oil Lubrication Systems

Connects manometers to circulating lines for accurate oil pressure readings.

Water Treatment Panels

Integrates gauge points across booster pumps and filtration loops. 

Steam Traps & Boilers

Adapts pressure sensors in thermal environments using PTFE-coated brass. 

Compressed Air Networks

Facilitates diagnostics with 1/4″ BSP or G-thread adapters on air regulators.

Fitting Pressure-Heavy Layouts

Getting adapter threads or angles wrong in early setups leads to high rework costs. We supply straight and elbowed variants, fully matched to your gauge port and process connection types.
 
You avoid compatibility issues while reducing dead zones in pressure lines. Our adapters support up to IP65 sealing with proper torque, helping you keep diagnostic points functional and leak-free over time. 

Having Doubts? Our FAQ

Check all our Frequently Asked Question

Can you match a specific thread type that’s not standard like ISO or NPT?

Yes, we can produce adapters with special threads including unusual metric pitches or older DIN variants. You just need to confirm the gauge and process side thread details. We support mixed thread formats on both ends if needed.

Do you supply adapters in elbow or offset styles for space-constrained layouts?

We offer straight, 45°, and 90° elbow configurations based on your equipment spacing. Body diameter and hex width can also be modified to clear tight panels or nearby fittings. Just share your dimensional constraints during enquiry.

What is the minimum quantity required for a custom adapter with electroless nickel coating?

We handle low-volume runs for special finishes, including nickel or PTFE-coated brass. For most sizes, we start from as low as 50 pieces depending on the coating and geometry. Share your finish preference and size to confirm MOQ. 

Can these adapters handle steam or oil-based media over long cycles?

Yes, our brass adapters are suitable for steam, oil, or compressed air lines when used within rated temperature and pressure limits. We offer designs with deeper threads and sealing options for long-cycle operation. Let us know your fluid type and cycle duration for evaluation.

How quickly can you ship parts if we need non-standard thread and coating combinations?

Lead time for custom thread and surface finish combinations usually ranges from 2 to 4 weeks. This depends on tooling availability and finish type. Early confirmation on specs helps us reduce production delays.
