Product Details:

The Insert Ring is a small yet vital component placed inside pneumatic tubing at connection points to push-in fittings. It offers several benefits:

• Prevents tube contraction when inserted into push-to-connect fittings, which is especially useful for very soft tubes like vacuum-type UD and polyurethane 

• Enhances pull-out resistance, reducing accidental disconnection .

• Essential for liquid usage, particularly water flow, to prevent leaks .

PISCO offers Insert Rings in a wide variety of metric and inch sizes:

• Metric OD x ID (mm): 3×2, 4×2.5, 6×4, 8×5/6, 10×6.5/7.5, 12×8/9/10, 16×11/13

SUS303 Equivalent Corrosion Resistance

The PISCO PP Series consists of polypropylene-bodied push-to-connect fittings designed for excellent chemical resistance, non-metal fluid contact, and cost-effective corrosion protection—equivalent in many ways to SUS303 stainless steel in non-extreme conditions.

These fittings are ideal for use in acidic, alkaline, or ion-sensitive fluid systems, where metal-free flow paths and lightweight construction are preferred.

Product Details:

The EG series uses antistatic (static-dissipative) resin, designed specifically for areas sensitive to static electricity. These fittings safely bleed off static build-up, preventing equipment malfunctions or hazards in electronics labs, cleanrooms, or flammable environments 

• PC-EG: Straight push-in fitting

• PL-EG: 90° elbow fitting

• PB-EG: Branch tee

• PU-EG: Union straight

• PV-EG: Union elbow

• PE-EG: Union tee
  Each supports metric tube sizes (4–12 mm OD) with threaded connections like M5, M6, R1/8–R1/2 

• Any anti‑static or ESD‑sensitive environment (electronics assembly, semiconductors, etc.)

• Locations with flammable dust or gases where charge build-up is hazardous

• Cleanrooms or labs where static must be controlled

⚠️ Always pair EG fittings with antistatic tubing or surfaces, and never mix with non‑EG fittings in the same circuit 

• Regular resin fittings do not dissipate static, so using them can allow charge build-up.

• In sensitive environments, EG is required to avoid malfunctions.

• EG is a simple switch: same functionality as standard push-in fittings, but made of antistatic material.

The Pisco Stainless SUS304 Series tube fittings are engineered for demanding environments where corrosion resistance, hygiene, and durability are critical. Made from high-grade SUS304 stainless steel, these fittings are ideal for food, medical, chemical, and high-temperature applications.
