Brass Oil Pipe Fitting

The NINGXING Brass Oil Pipe Fitting combines a threaded connection with a toothed hose barb in a compact brass body. The barb improves hose grip when secured with a suitable clamp, while the threaded end follows DIN ISO 228 (BSP) specifications.

Available configurations include straight, L-type, T-type and Y-type models. The straight model is suitable for direct routing, L-type fittings change hose direction, and T-type or Y-type fittings support branch connections.

Configuration Comparison

Selection Guide

Choose the fitting according to hose routing, available space, flow direction, pressure, temperature, vibration and maintenance access.

A Brass Oil Pipe Fitting is suitable for direct hose routing without sharp bends. An L-type fitting is designed for an immediate 90-degree direction change. A T-type fitting supports flow splitting or combining through three connection points. A Y-type fitting is suitable for angled branch routing and smoother hose transitions.

For branched fittings, confirm the inlet and outlet arrangement, branch size, flow direction and need for valves or other flow-control components.

Specifications

The standard Brass Oil Pipe Fitting information indicates a working pressure of up to 16 bar and an approximate temperature range of -40°C to +100°C. The thread standard is DIN ISO 228 (BSP). Available materials may include brass grades such as C360 or C377, subject to confirmation. Polishing and electroplating are available for selected models.

Actual performance depends on fitting size, hose construction, clamp type, sealing method, fluid and operating conditions. Strongly corrosive fluids and oxygen-rich applications require separate compatibility evaluation.

Size Range

The following dimensions are based on the supplied BSP thread information. Confirm the exact model, hose size and sealing configuration before ordering.

For L-type, T-type and Y-type models, confirm the complete dimensional drawing because outlet size, branch size, overall length and orientation may differ.

Thread Sealing

Before installation, identify whether the connection is BSPP or BSPT.

BSPP is a parallel thread that usually requires a washer, O-ring, gasket or other face seal. BSPT is a tapered thread that usually requires compatible PTFE tape or liquid thread sealant.

BSPP and BSPT should not be treated as interchangeable. Do not use sealant to compensate for damaged or mismatched threads. Avoid excessive tightening, which may damage the fitting or mating port.

Hose Clamp Selection

Select the clamp according to the hose outside diameter after installation, working pressure, vibration, temperature and environment.

The hose should be fully seated over the barb, and the clamp should be positioned over the barb area without cutting or deforming the hose.

Applications

Tanker Unloading

The Brass Oil Pipe Fitting is suitable for compatible hose and pipeline connections in petroleum and chemical unloading systems. Straight fittings support direct routing, while L-type models can help manage hose direction. T-type and Y-type fittings may be used in auxiliary distribution or sampling lines.

KZD-series double shut-off quick couplings may be used with the complete system to reduce leakage during disconnection. All components should be selected according to pressure, fluid and connection requirements.

Construction Equipment

The fitting is suitable for compatible low- or medium-pressure oil and fluid lines on excavators, cranes and other construction equipment. L-type fittings can help route hoses in compact compartments.

Because construction equipment is exposed to vibration and movement, hoses should be supported independently where necessary. High-pressure hydraulic systems require specialized fittings rated for their operating conditions.

Industrial Equipment

The fitting is suitable for compatible water, oil and compressed-air connections in factory automation, cooling equipment and fluid-transfer machinery. The compact design is useful where installation space is limited, provided that sufficient access remains for tightening and maintenance.

Petrochemical Piping

Brass fittings can be used in many general oil and fluid applications. For aggressive chemicals, high-purity fluids or special process conditions, confirm material compatibility, pressure, temperature and certification requirements before use.

Agricultural and Irrigation Equipment

The Brass Oil Pipe Fitting is suitable for compatible water, oil and air connections in irrigation systems, sprayers, agricultural machinery and small pumping units. For fertilizers, pesticides or additives, verify compatibility with the fitting, hose and sealing components.

Mobile Service Equipment

The fitting is suitable for service vehicles, portable compressors, lubrication units and mobile fluid-transfer equipment. Protect the fitting from impact and use hose supports where repeated movement or vibration may occur.

Installation and Maintenance

Before assembly, confirm the hose size, barb size, thread type, pressure, temperature and fluid compatibility. Clean the fitting, hose and mating port to remove dust, oil residue and other contaminants.

Push the hose fully over the barb and secure it with a suitable clamp. Use the correct sealing method for BSPP or BSPT connections. Avoid excessive tightening of threads and clamps, as excessive force may damage the fitting, port or hose.

Ensure that the hose follows a natural route without twisting, sharp bends or excessive tension. For L-type fittings, confirm the outlet orientation before final tightening. For T-type and Y-type fittings, verify branch connections and flow direction.

Always depressurize the system before maintenance. Inspect the fitting, hose, clamp and sealing surface for wear, corrosion, deformation or leakage.

Ordering and Customization

For standard orders, specify the thread size and standard, BSPP or BSPT requirement, hose inner diameter and barb size, fitting configuration, branch size and quantity where applicable, material, surface finish, working pressure, temperature, fluid type, quantity and packaging requirements.

NINGXING supports OEM customization based on customer drawings, samples or technical specifications. Customized dimensions, thread configurations, materials, branch angles, port arrangements and surface treatments can be evaluated.

FAQ

What fluids can it handle?

It can be used with compatible water, air, oil, fuel, hydraulic oil, steam and certain inert gases when the pressure, temperature and material ratings are suitable. Aggressive chemicals and oxygen-rich applications require separate evaluation.

How do I choose the size?

Match the barb size to the hose inner diameter and the BSP thread to the mating component. For T-type and Y-type fittings, also confirm the size and function of each branch.

What is the pressure rating?

The standard information indicates a working pressure of up to 16 bar. Confirm the rating of the exact model because performance depends on size, hose, temperature, configuration and connection conditions.

What temperature can it withstand?

The typical range is approximately -40°C to +100°C. The actual limit depends on the fitting, hose, sealing components and conveyed medium.

Can non-standard sizes be manufactured?

Yes. NINGXING supports OEM machining based on customer drawings or samples, including customized dimensions, threads, materials, configurations and surface treatments.
