Brass Tube Inserts

When push-fit tubing systems fail under vibration or thermal shifts, insert stability becomes a top concern. Brass Tube Inserts offer form-fit reinforcement that supports soft tubing across repeated pressure cycles and assembly changes.

Tube Outer Diameter (OD) Compatibility

1/8″ – 1″ (3mm – 25mm)

Tube Inner Diameter (ID) Compatibility

0.06″ – 0.75″ (1.5mm – 19mm)

Overall Length

0.25″ – 1.5″ (Flanged types: +0.2″)

Insert Type/Form

Standard, Flanged, Collarless, Ribbed (High-Retention)

Material Grade

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

Product Description

We machine each insert to match inner diameter tolerances while offering retention ribs, flanged stops, or collarless ends as needed. This ensures better seating, stronger pull-out resistance, and smoother flow without stressing the tube wall.

Pressure Rating

50 PSI – 300 PSI (3.4 – 20.7 bar) (Ribbed types: 300 PSI max)

Temperature Range

-40°F to 250°F (-40°C to 121°C) (Nylon/PE tube compatible)

Internal Flow Diameter / Bore

0.05″ – 0.7″ (Matched to tube ID for smooth flow)

External Diameter (Insert Body)

0.1″ – 0.8″ (Designed for snug tube fit)

Collar/Flange Diameter

0.2″ – 1″ (Flanged types only)

Number of Retention Ribs/Serrations

2 – 6 (Ribbed types for high-vibration resistance)

Compatible Fitting Type

Compression, Push-to-Connect, Barbed

Compatible Tube Material

Nylon, Polyethylene (PE), Polyurethane, Copper, PEX

Finish/Coating

Natural Brass, Electroless Nickel (ENP), PTFE-Coated (Low Friction)

Standards Compliance

ASTM B16, ISO 8434, SAE J512, NSF/ANSI 61 (Potable Water)

Weight

0.005 lb – 0.1 lb (Size-dependent)

Technical Advantages

We produce insert forms in standard, flanged, and ribbed styles, each machined to match exact tube ID for tight inner contact. The rib count ranges from 2 to 6 to resist axial movement in dynamic or pulsing systems. All materials comply with ASTM B16 or CW617N grade requirements for corrosion and pressure resistance. Electroless nickel and PTFE finishes are available for smoother insertion and lower friction under dry fitment.

Industry Applications

Automotive Vacuum Lines

Inserts prevent wall collapse and pflegen seal integrity in under-hood PE tubing connections.

HVAC Control Assemblies

Collarless variants support tight routing in multi-loop climate control tubing systems.

Refrigeration Charge Lines

High-retention ribbed inserts handle repeated pressure and expansion cycles without tube deformation

Water Filtration Units

NSF 61-compliant materials allow safe installation in potable water-compatible push-to-connect joints.

Compressed Air Equipment

Smooth bore inserts pflegen internal diameter continuity to avoid flow disruption in pneumatic loops

Agricultural Sprayers

Flanged inserts resist loosening under high shock or field vibration from pump-based delivery systems.

Strengthen Connections Where Tubing Alone Can't

Flexible tubing often bends or shifts under routine load and temperature change. Our Brass Tube Inserts give internal support, letting you avoid clamp failures and crushed walls.

They hold their shape during tube rework, supporting repeat assemblies without weakening grip strength. Across form factors and finish types, we help your system stay aligned and flow-ready.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

Can you match the insert rib design to our specific tube flexibility and vibration range?

Yes, we adjust rib height, count, and pitch based on your tube wall thickness and vibration frequency. This avoids over-compression or loosening during long-term use. We also offer grip trials if required for edge-condition tuning.

How flexible is your MOQ for mixed-size insert orders in a single dispatch?

We support small volume mixes when you need different insert sizes for prototype runs or line changes. Batch-wise packing or kit-wise sorting can also be arranged. We avoid forcing single-size bulk constraints on diversified tubing projects.

Can we ask for insert forms that eliminate flange overhangs for tight manifold routing?

Yes, we supply collarless and low-profile forms that reduce axial interference in dense layout systems. These help pflegen tube clearance without increasing part count. We modify end chamfers too, based on your connection depth.

How do you ensure the bore diameter aligns with tube ID when tolerances shift between batches?

We check incoming tube samples or use shared tube specs before defining insert bore fit. Our machining compensates for nominal ID deviation to avoid loose seating or excess friction. Each lot follows a fixed bore range with cross-checking on random pull tests.

What’s your typical lead time when insert finish types or alloys differ across the same order?

Lead time stays under 3 weeks for most variations, including nickel and PTFE-coated units. Parallel machining and staged coating allow faster output even with mixed types. We confirm feasibility early to prevent hold-ups from mid-cycle change requests.
