Today, I’m proud to share something our team has worked on for a long time:
an extra-large, heavy-duty latex membrane with 600 mm diameter, 1500 mm length, and 2.5 mm wall thickness.
This is a milestone for HOWDY. It shows what careful engineering, steady hands, and patient testing can do.
Why this matters
Large-scale testing needs stable boundaries. Small wrinkles, thin walls, or weak seams can bend the data.
This membrane was made to stay calm under pressure—so your results reflect the specimen, not the sleeve.
What you can expect:
- High stability: 2.5 mm wall for strong radial support in big rigs and custom chambers.
- Consistent geometry: tight wall thickness control across the full length.
- Clean surface finish: smooth, uniform surface helps sealing and reduces fold formation.
- Factory QA: every lot is tested for wall variation, visual defects, and leak tightness.
Core specification
| Parameter | Value |
|---|---|
| Inner Diameter | 600 mm |
| Length | 1500 mm |
| Wall Thickness | 2.5 mm |
| Base Material | High-purity natural latex |
| Use Case Examples | Large triaxial/model cells, calibration chambers, custom pressure sleeves, special fixtures |
If your fixture or end caps are unique, we can discuss flanged ends or other custom shapes to help with alignment and sealing.
Who is it for?
- Research labs running large geotechnical or materials experiments
- Calibration facilities that need stable, repeatable boundary conditions
- Engineering teams building custom cells with ports, collars, or special end hardware
If your setup is “non-standard,” you’re our kind of partner. We design for real lab life.
What we tested before this announcement
We validated the membrane with:
- Dummy-cylinder pressurization to check for wall uniformity and early leaks
- Step-pressure holds to observe creep and seating behavior over time
- Mounting trials with alignment jigs to reduce folds near the ends
The goal was simple: fewer surprises on your frame.
Availability, samples, and support
- MOQ & lead time: provided on request (no public pricing; we’re B2B only).
- Samples: small pilot quantities can be arranged for fit and mounting trials.
- Documentation: we share a short mounting SOP, a leak-check card, and basic maintenance tips.
If you need a different length, a modified diameter band, or a special edge detail, tell me your drawing and stress range—we will advise the closest workable option.
A note from our team
We started HOWDY with a simple promise: “latex membrane free”—advice first, sales second.
If you’re unsure whether this size is right for your rig, message us. We’ll help you decide honestly.
Thank you for trusting us with your tests.
