Single-piece pricing is $8.40 for sample orders, $7.15 each at mid-volume (around 100 units), and drops to $5.80 per unit once you hit 500 pieces — that's roughly a 30% reduction form list, so most buyers go with the higher MOQ.

Pneumatic Hydraulic Quick Coupling

It basically replaces three separate fittings in a standdard air line setup, your total system weight by 83% compared to the brass-and-copper stuff you're probably used to seeing on truck trailers, and you'll pair it with Polyamide or Hytrel tubing on teh same SAE7.89 spec.

Pneumatic Coupling Applications

We've shipped these into bus fleets and off-road vehicles where vibration is constant — the brass core handles that, while the composite jacket resists corrosion even when salt spray is a daily factor; it's not meant for high-presure hydraulic lines though.

Quality Pneumatic Couplings

You're looking at a -40°C to 115°C range that covers most cabin and chassis environments we've seen, with female push-in coupling avaliable in green, yellow, or white; we usually keep all three in stock but check lead time before ordering custom color batches (typically 20 days or so).

Pneumatic Coupling Color Options

Also, every shipment comes with a COA for the batch generated from HPLC data we take in-house, so if your compliance team asks about traceability we've got them covered without sending them hunting.

Frequently Asked Questions

What is the minimum order quantity for the TB-RH-PC coupling?

We typically start at 500 units per size and color, but we can discuss lower quantities for first-time orders or sample requests.

Does this coupling come with SAE certification documentation?

Yes, it's built to SAE7.89 standards, and we can provide a certificate of conformance with each shipment.

Can I get the coupling in a color other than green, yellow, or white?

Currently we only stock those three colors, but custom colors are possible for larger volume orders—just let us know the RAL code.

What is the lead time for a standard order of TB-RH-PC couplings?

Stock orders usually ship within 7–10 business days. If we need to produce a fresh batch, lead time goes to about 3–4 weeks.

Is this coupling compatible with nylon tubing, or only polyamide and Hytrel?

It works with both polyamide and Hytrel tubing. Nylon is a type of polyamide, so yes, nylon tubing is fine.
