Parker Hannifin offers a broad range of thermoplastic fittings including TrueSeal™, Fast & Tite®, Par-Barb, and Mini-Barb. The True-Seal™ push-to-connect fittings are light weight, reusable, and connect to plastic tubing without the use of tools. Fast & Tite® fittings provide a tight, sure, leak proof seal without clamps or adjustments. Par-Barb fittings are designed to generate the maximum gripping and sealing power when combined with a hose clamp. Mini-Barb fittings use a special tapered #10-32 UNF threaded design to compensate for threaded port connections which are oversized or misaligned.
